I highly doubt that such AI would be capable of playing the poker game. Yes AI is very advanced tech right now, but you need to teach the AI, and its logic is formulated based on those learnings.
ChatGPT is not specific to playing games. There is just zero chance it may even be able to think stuff about it.
Your opinion is very valid and more than I feel that you have used it, I cannot say much because I have not interacted with the AI, but you are one of the few people who are clear in its scope, some see the AI as the Holy Grail, and despite I know that I have not interacted, I know that it has a long way to go, because this is like when the Mark1 came out, everyone was amazed at what it could do, it was just 1 prototype of what is now something very normal, minituaired, and this is an analogy simple of what AI can represent today that what it will be in 3-4-5 to 10 years that will be something impressive.
Yeah right, the improvement will continue and who knows if what AI can bring after 5-10 years, we really don't know if how accurate and how it can be developed. But one thing is also for sure that in the even that AI will have a better understanding of how the possible outcome, gambling owners will also adjust and will do the best counter to make sure that they still have the advantage.
In the sense of pushing things to gambling, adjustments from the other side will need to anticipate, it's business and they will do everything to protect the business.
