Three things:
1. If you are losing in gambling, around 90% or even more of gamblers are like you.
2. If you gamble because you are looking for money, quit, you will not find it there.
3. If you want to gamble with a higher probability of winning and not just guessing out of random possibilities, try sports betting. Choose matches and games which you are very familiar with.
Good luck!
This suggests that gamble only for fun and not for money.
You will lost most of the time but can win one big amount which will make you millionaire and also recover all your loses. Most of the gamblers play with this hope. There is no strategy for winning in gambling.
