Yes,I found success (win) in gambling many times but most of the times I lost,just understand the many and most so totally we are going to lose our money more than winning here,so if your intention is to make money then invest on something with less risk.
It is nice that you realized it before itself before you either got addicted to it or had learnt the hard way by losing money and some relations as well. it is dangerous if you start playing to just to win from gambling and on looses you will get more frustrated and nothing else.
