That's gambling man.
Sometimes you lose, others you win.
But usually loosing is a bit more frequent!
... and losing is always bigger and more painful !
gambling is about 99% losing

Actually it is not. Bad decisions make it that way. People seem to not realize how to stop and when to quit betting chain.
If you are tilted and on losing streak possibility of losing everything is quite high. Mathematically there is no way that you would have 99% chance of losing every bet/roll/game.
