Frankly, I don't think gambling actually helps anyone at all. It is more for fun, games and entertainment. I do not think there're rich people out there who think their lives are worse off without gambling.
That said, there are some things you can learn from gambling that could be good for you, including money management, maths, self-control and discipline.
I agree with you mate, we can learn from gambling, money management, maths, self-control and discipline like you said, But i disagree with you when you said, It can't help you our your life, because fun and entertainement can be a positive things to your live and increase your mind power when you win, I mean you feel too good.
