Why aren’t these perfectly in focus?

I watched I guy just after Christmas brought his new rebel to a group photo shoot. He starts taking shots and it pops the flash. He pushes it down and it pops up again. I wanted to help him but you have to explain aperture mode, you have to explain your ISO needs to be high enough to make sure the shutter speed is fast enough to get a sharp image. This guy gave up and started using his phone.. And camera manufacturers complain they are losing sales on the low end market, well this is why.
That's mostly true, too complex. Alas, (P)rofessional mode also stops the pop-up flash and generates the exact same exposure as <Auto>. I actually would have been able to help...

All four images are out of focus because the focus is not working...
There is no problem with the camera settings that I can see. In the EXIF it says it's set to f/5, ISO 500 and 1/400 shutter speed. Shutter speed is plenty fast to freeze the movement and the other settings are fine (though these images look a little underexposed).
In the last image, note that the fence/gate is sharply in focus. I think this is just luck. The fence happens to be at the correct distance for where the lens' focus was set. In the other three images everything is closer and nothing is in focus.
In the EXIF data it says "AF Points In Focus (Used): none / manual focus / 0 available"
This appears to be confirmed by Paul (Chg_Canon) with DPP, which shows no active AF points.
There are several possible reasons...
1. The AF is turned off at the lens.
2. Camera is set to Back Button Focus and user failed to press the button. If NOT set to BBF, the AF system is activated by half press of the shutter release button... so you really can't take a shot without first activating focusing.
3. It also might happen if there is no communication between camera and lens for some reason, or the AF system has failed in the lens or camera. If this were the case, I don't know whether the AF point would appear active or not (in EXIF or DPP). If you have another lens, try it on the camera to see if it's able to autofocus. If possible, try the lens on another camera to see if it's able to autofocus. This is a simple way to tell if one or the other is faulty. If you don't have a 2nd camera or lens, maybe a friend or a local camera store?

I take lots of action shots in my focus is seriously perfect.
Should I be looking at camera issues?
Thank you

The whole image is a bit "soft", indicating a slip-up in camera technique. I would look at that before suspecting the camera or lens. Mashing the shutter release like you were killing an ugly bug can produce effects like are shown in your photos. Unsteady position, coupled with zoom at maximum could be a contributing factor. Is your camera control set to release at focus, or the alternative of release whenever, ignoring focus?
