As you told us about game, it is very difficult and also very attractive game, it can be addicted gamblers, but winning is very difficult because this game is pure luck base game. So i guess only few gamblers have won in this game, and mostly they have lost.
The main thing is that in gambling there is nothing specifically called winning. You win or you lose depending on when you stop. Because stopping the play is the biggest win and the only win for any player. If you stop and not gamble your till now earned wins then you are at a profit and you should cash out and never come back. But the casino is the winner in 99% cases because this does not happen.
Every gambler plays with their win only to lose it again. So the wins comes to you temporarily and then goes back.
