I am sure that it will never happen. In the short term, poker is very dependent on luck. In the long term, it doesn't. At the Olympics, the best athletes compete. I already see the first problem there, because first you would have to qualify for it because otherwise theoretically everyone could participate there. Secondly, I see a problem in the duration. In order to choose the really best, one would have to adapt the rules in poker or have several tournaments played. Both are time-consuming.
I therefore see a lack of foundations to consider it an Olympic game.
