I was prepared to buy a Canon refurbished T6i to replace my T3i due to my present camera having 32,000 shutter activations. Then I did a search here on UHH regarding a T6i vs the T3i and many responders said "keep the T3i". Not sure why, but my real question.... is a 32,000 shutter count getting high enough to justify replacing the camera which I've had for about 3 years. I use it almost exclusively to shoot the college soccer games for my son who is Head Soccer Coach. I use the Canon 70-200mmL f/2.8 lens and get great results.

I haven't seen Canon "rate" their shutters on a lot of their more recent models, the way they have done in the past. But in general the Rebel series cameras were considered to be "good for" about 75,000 actuations. (For comparison, 80D, 70D, 60D and other xxD-series: 100,000... original 7D: 150,000 and current 7D Mk II: 200,000.... 6D series unknown, but likely around 100,000.... recent 5D-series: 150,000... 1DX Mk II: something like 400,000.)
That being the case, your camera has lived about half its life.
But, this is just a "mean time between failures"... Only an estimate of shutter durability based upon the design and materials used, as well as track record of similar in the past. Some cameras don't live that long. Others live a far longer and happier life. There are Canon out there that have done 3X, 4X their MTBF and are still working fine.
And a shutter isn't the only thing that can fail in a camera... It's just the most mechanical assembly in a modern DSLR, and prone to wear. But solid state electronic parts can fail, too. Part of the reason that shutter count is referenced goes back to the early days of digital, when they were just basically film cameras with a sensor added. Without film to buy and process, it turned out that folks shooting digital took a lot more shots... a whole lot more! Olympus learned the hard way... a really nice digital they were offering was immediately popular with pros and advanced amateurs alike. But it turned out that the film-camera shutter they'd used was only good for between 15,000 and 20,000 clicks. Many of the buyers of the camera were shooting twice that many images a year! So Olympus found themselves replacing shutters under warranty a lot... sometimes even more than once in a given camera. No doubt that was expensive, so Oly and everyone else stepped up and developed more durable shutters to use in their digital cameras.
In my experience, if a camera "lives" past it's first week or month out of the box, it's usually going to be good for a lot of years use and at least as many "clicks" as it was rated. Only a few Canon models' shutters have seemed to fall a bit short. For example, 40D were known to have somewhat earlier shutter failure than other models in that series that came before and after.
So unless your camera has seen unusual abuse or has gotten wet or is an oddity, it's very likely got a lot of useful life left.
However, maybe you would find some of the newer model's features helpful for your purposes.
For example, T6i has a much more advanced autofocus system than T3i. Your camera has one high-performance "dual axis" AF point in the center, all the rest are lower performance single axis type... not great for fast acquisition or tracking moving subjects. In contrast, all of the T6i's AF points are "dual axis" and the center one is further enhanced "diagonal dual axis" type. Plus, T6i has a lot more AF points! The T6i's 19-point AF system is nearly identical to the 70D's (the only diff I'm aware of is that 70D has Micro Focus Adjustment feature, T6i/T6s don't)... The 70D in turn inherited a slightly "dumbed down" version of what was used in the original 7D. And the original 7D was and still is respected as a high performance "sports/action" camera. It has some other enhancements compared to 70D and T6i... but they both benefit a lot from what Canon learned with the 7D.
The new 77D and T7i apparently will have 45-point autofocus similar to what was introduced in the 80D. While that's quite good too, it's not as high performance as the 65-point AF in the 7D Mark II. But any of these newer models offer significant advancement over your T3i's autofocus system.
Continuous shooting frame rate is another thing that's often important for sports/action photography. Your T3i's top speed is about 3.5 frames a second. T6i/T6s can do 5 fps. T7i/77D are supposed to do 6 fps. 80D manages 7 fps and 7D Mk II does 10 fps (orig. 7D was rated to do 8 fps, but often slowed for metering and AF).
Shutter lag is another thing of concern to sport/action shooters. The shorter the better to be able to time peak action shots. All Canon DSLRs are pretty good... But some are better than others. Your T3i's shutter lag is 90 milliseconds. T4i and T5i improved slightly to 75ms. I don't know about T6i/T6s... but T7i/77D are slightly improved to 70ms. For comparison, 70D and 80D are 65ms and 60ms, respectively... And 7D Mark II is 55ms. Top of the line 1DX Mark II's shutter lag is user-adjustable between 55ms and about 35ms. At the other extreme, the most entry-level Rebel T6/1300D's lag is 120ms.
Finally, control access is another thing that can be important. For example, sports shooters often want more direct access to Exposure Compensation or shutter/aperture controls. They want to be able to make changes while keeping the camera to their eye and their eye on the action. T6i's controls are typical for Rebel series... many functions are "two-step". You first press a button, then turn a dial. In contrast the T6s, 77D, 80D have more direct access to some of the most used controls... simply turn the dial.
Back Button Focusing is a popular technique among sports photographers, too (primarily because it allows one to use AI Servo focus mode as a default setting). While I think it's possible to do BBF on all Canon DSLRs (and most EOS film SLRs), with some it's more conveniently done. On T6i/T6s and lower models, including your T3i, you have to reassign the AE Lock "*" button to control focus. On 77D and all xxD models from 40D onward, as well as all models upward, there's a separate "AF On" button that can be used instead, leaving the AE Lock function more quickly and easily accessible.
Frankly, maybe your best bet would be to instead add a lens for use on your T3i. Canon 70-200/2.8 are excellent for sports, especially on an APS-C model such as we're discussing. But a fast focusing 24-70mm f2.8 or similar also can be very useful. Or a 300mm f4 IS, to get shots at the other end of the football field! I always consider lenses more important than the camera they are used upon, so long as the camera is relatively up to modern spec. The T3i is 18MP (7DII is 20MP, T6i is 24MP... neither is all that much of an increase in this respect). And I shot sports for years with cameras that have essentially the same AF system and were little faster than your T3i. It's not like it hasn't already quite capably made 32,000 images for you! Sometimes the best thing to do is keep the camera you know and add optics that will make it even more useful.
