Artificial Intelligence was created as an aid to enhance the human ability and it would be very unfair if it's allowed to be used in casinos, not only that but also those casinos could go bankrupt because alot of people would see it as an opportunity you recover their losses
As for me, I want to believe personally that the use of artificial intelligence system in gambling under a particular casino will not be hundred percent effective andbthe out will not always be what the gamblers could expect, these AI were also programmed and has limit to the way they function and the extent they go far reach, if it had been that profitable then almost all the gamblers would have chose to make use of an artificial intelligence system to gamble and they won't have a cause to loose their games anymore, AI is more applicable is some areas of gambling and not best applied to making bet predictions.
Perhaps this is more about collaboration between human intelligence and AI capabilities can lead to maximal returns as they would synergise the best of each world. People adapt, learn, etc,..., so we can be successful in challenges under varying circumstances an in complex environments, that is really part of our evolution as animals an humans.
