You can win in gambling only when you have a well thought strategy before betting and also you bet money you can afford to lose, have a lot of discipline to make this strategy work.
Basically 0% of people in the world can achieve this, but you can try. If you don't follow the rules you will play gambling without thinking and destroy yourself. Better quit.

The best I can tell you is, you will be richer and have more money in your pockets if you don't gamble at all. This one too still very difficult to achieve.
