There are different parts of gambling, and AI might be able to master some of them, but the main thing is that casino businesses can't let that happen, because if AI starts gambling with an accuracy of just 70%, that will be a disaster for gambling platforms, they will only have two options if something like that happens, they will either use AI to counter the situation or simply ban using AI models in their casinos and those found will get banned forever.
Also, if an AI model is created that gains success in gambling, it won't be easily accessible for everyone and developers will surely large a very large sum to give access to anyone because anyone can easily get the return on their investment with the model using any cryptocurrency exchange.
I'm not sure but if I'm the developer or if I will manage to create working AI, maybe I will keep it and use it to earn decent amount of money before it will be exploit. Sooner or later the house will counter it and the chances to will be slim.
That's the right to do if ever you create a working AI that will help you win in sports betting, but of course, I will diversify and will not try it on one casino, because they will be suspecting you of using a system too consistently win, even if you're a good bettor its important to diversity and use at least 3 to 5 bookies or casinos so if one traced you and flag you, you still have 3 or 4 casinos to use your system.
But the majority will use it in a casino, it is not that it can be so easy to determine that the result is made by an AI, it differs when you can apply the AI to a casino with games such as dice, roulette, it is easier to determine that it is used an AI than in sports betting, I think so because in a bet that is for a specific sport, the algorithm of an AI is easier to hide in a casino, or it doesn't even need to be inside the casino, that's why I think that things are not that easy for a casino to determine what is AI. besides, everything is AI, anything is an AI, it's the fashion.
