AI will be limited in its capabilities at this time or later, of course they will not be programmed to exceed the limits of human capabilities too, after all, what's the fun of using AI technology in gambling, in my opinion, it doesn't really look interesting, let alone fun, it will definitely be boring using it.
That simply means they are useless when it comes to gambling. To increase our chances of winning, we should be the ones to develop our skills because relying on AI will likely lead to long-term losses. In my opinion, AI can be used in sports betting to provide information and statistics, but that data alone is useless if we cannot analyze it in our favor.
If AI were very useful in gambling, casinos would probably be threatened by it, but honestly, I haven't heard much about that.
AI can be in different form as what others said before. Auto-betting is an example of AI. I bet you already recognize it. Now will you still say that it was useless? It may not make us win but at least they can automate our game play to allow us to do other things for a while like eating or when you need to go to the bathroom, etc.
You even said that you can use AI in sports betting. See? Developing our skills in some gambling games is possible but for the majority of the games, no, so don't ever attempt it because you will only waste time and money. It's better to do a research about which games are skills applicable and what aren't.
