Is it harder than learning how to program? I've played poker a bit and learned being tight aggressive (just some basic strategy, the most "advanced" concepts I learned were polarizing hand ranges, implied odds and having a poker tracker in your games and what all those things meant).
I'm assuming you mean learning how to program as a profession, but it's a difficult question to answer. It relies on so many factors, both in terms of the "market" you're in, as well as who you are as a person. Based on the average person that tries to become a professional programmer vs the average person that tries to become a professional poker player, I'd say it's considerably more realistic to become a professional programmer.
But again, if you want to find out just play the game and see how you do. Find stakes you can beat and try to move up.
