Gambling is all about random number generation, and provably fair scheme provides guarantees that casino doesn't cheat, but we also know that humans are horrible random number generators - we are very easily predictable.
not all gambling are based on generating random numbers . what card games like poker ? that is an example of skill based and you are using a card not numbers . there is not right or wrong in generating a number because that is random but i think we it comes to solving something , ai or bots can work well versus humans .
When you play online poker, I think the calculations are using computation from the script, and if AI has replaced the computation system, I think they could use AI for the calculations. The player still using their skills to play poker but the opponent, which is the house, they could use AI to play for them.
So, theoretically a casino can observe how you place your bets, then predict your next bets and make their own bets (they always go first) accordingly.
they can observe your bets but they cant predict your next bets not unless if they are not fair . also not all gambling game is in versus mode ( dice game for example ) i think this games are more safe .
Predicting what the next bets from us still difficult to them because of we bets base from the situations in the poker table and I think the AI now are not in that phase and maybe it will need to develop more so AI can work as we want.
But I am sure that in the future when the AI is grown more than now, it can help not just the casino but in the other field. We will see something new in our future and who knows what we saw in the movie will happen to our real life.
