Do you mean to say that the casinos are the ones that will win or lose? I know that the casinos stand more chance than gamblers in this case of AI use. In most movies that I have watched just like you spoke about it too, we can see that the information they try to pass is how AI is being favourable to some companies and we know that AI can be more helpful to casinos than gamblers.
I did not know how to explain, with AI the casinos are guaranteed their profits , but if Specialised attacks arise with very advanced technology in AI with quantum technology it is Possible that they could make them lose, but of course I am talking about a case where this becomes very advanced and there are those tools, it is a possible scenario where it could happen. There are so many things going on in the world that you can't ignore a case like that.
