I’m sure it’s only a matter of time before someone creates and AI bot that can sit around making thousands of bets per day and winning at a rate slightly higher than the average gambler. I still don’t think AI can beat the odds over a casino in the long run, but I imagine it could probably bet a massive amount of money with a ton of bets to make gamblers inflate their amount bet numbers like never before.
In a way this has already happened, in the stock exchange. It's called High Frequency Trading (HFT), and it's been happening since more than a decade or two already.
Basically the bots try to find a good opportunity and they buy or sell stocks, all of this in milliseconds. There's no way a human can compete with this.
In terms of betting, I guess most casinos have slower interfaces so I don't think they provide a similar infrastructure like the stock exchange.
