It would be hard for me to imagine the truefulness your comment; it definitely stabilizes my camera against the wind when taking selfies.
Perhaps the more expensive ones do not need weights to hold it down for stabilization. People are probably pleased by your comment so as to justify the money well spent on their expensive tripods
By the simple law of physics, the added weight lowers the center of gravity and increases the mass of the whole set up which will hold more firmly to the ground.
I would challenge my setup against any expensive tripods, to see which camera will get blown off first.

So let's look at what you have - an aluminum tripod that costs $36 new, and has a load capacity of 10 lbs. If you put a DSLR and lens that weighs, say 5 lbs, and you put a camera bag on the hook, and that bag and contents weigh more than 5 lbs, you have just exceeded the tripod's load capacity - not a good thing. There is also a loss of stability when the bag swings in the wind. The center of gravity may be lower, but it is a pendulum. And the added swinging weight does not address the inherent lack of stability in it's design.
Stability in a tripod. When a tripod is stable, it will adequately dampen vibrations - from wind, shutter vibration, mirror vibration, etc. The higher the magnification the more stability you need. My opinion, arrived at over 51 yrs of camera use in studio and the out in the field, suggests that the Ravelli is anything but stable with anything more than a wide angle lens and a VERY light camera. The construction of the tripod where the legs attach to the top is cheaply designed and of poor quality - which is where you will see the most instability. If you compare it to a real tripod you'd immediately see the difference, and why better tripods are in fact, better.
A camera blowing over is not the reason you spend more for a stable tripod - you also want it not to vibrate, spoiling image sharpness. Any tripod is susceptible to blow-over - even the $1200 ones - and blow over is not an indication of instability, it's more an indication of someone taking unnecessary risks with their gear.
Your Ravelli will do what you want - let you take great selfies on windy days as long as you don't exceed the total load capacity and the wind isn't too strong. But it is no match for a real tripod.
This is just an educated opinion - it is not intended to mislead or be untruthful. And I suspect your's is as well.
But don't embarrass yourself by suggesting that there is no reason to spend the correct amount of money to get the support needed. In my opinion, $36 buys a toy that will fail when a critical plastic part breaks, weakened by UV exposure or over-stressing. It could be a leg lock, the hinge at the top of the leg, or the head itself, particularly the hinge which rotates the camera from landscape to portrait, which is made mostly of plastic. I wouldn't put anything valuable on it if I were you.
You shouldn't take my word for it, however:
