football betting or sports gambling in general is more easier and more predictabe than a poker or card based game . so how can you say that no all gamblers became succesful in betting on football matches ?
I disagree sports betting can be predictable but it's not easy to win. I think maydna's confused or just misread the first post, OP didn't move from sports betting to poker.
But to be honest, the poker game is too difficult to learn as I try to learn, but I failed over and over, maybe it because I don't have interest in the poker game or maybe a poker game was really difficult.
For starters it can be difficult but once you memorize the combinations it's not that complicated to play and win.
