Thats right, this could be one of the factors.I would say large stakes would put a player at a low priority of that container (unless they have lost ridiculous amounts and long term RTP needs to correct itself) but there's no doubt that live isnt really "live" but controlled by an RNG with the live portion being for show purposes.
For example; lets imagine you are playing roulette with 200 different players. And you happen to be the one placing the biggest bets. This would certainly impact the choice this container makes.
Im not saying you will not be able to win if you happen to be the biggest better, since many other factors are calculated in aswell.
For example; When you have a bad rtp, or when your rtp is higher, this will also impact it.
