AI will surely affect gambling in the area of Analysis and predictions which already people are using AI, but the truth is I do not believe there would be any greater chance of profitability using AI, Gambling site would create an alternative system to avert such and can also make rules or protocols to detect use of it, of which AI cannot really tell because we have different gambling sites/casinos so I believe the data will be irregular unless gambling was a unified system like Trading then her application would have been a bit relevant.
I'm not sure AI can actually analyze and make good predictions for people. Remember that even as a bettor that gambles using your own brain to make analysis, some of the bets that you lose is not because you didn't make a wise decision, it's because the outcome is bigger than what you can control. Haven't you use a big game to bet against a small club and yet the minor team you never expect beat the major team, it happen and you can't help it but accept it that way.
Do you also know that emotions is what AI can't predict, players can fight in a field over argument and one may over react or go extra length and then bag a red card, this is what AI can't do. You don't know if anyone can go injury, it can happen anytime any moment as I said, some situations aren't something you can control, they are part of he game and no matter you try to avoid them, they must surely happen.
