mostly will earn some profit on strategy based game..like poker or pvp
but for dice type of gambling need good luck to have good profit..
Only on strategy type games can you make a profit from gambling. The other games you play are just winning from pure luck. And as everybody knows, luck runs out eventually.
If you have bad luck where you can not even win on a scratch ticket, don't bother gambling as you will lose all the time and so much.
Yes it is really hard to make some good profit. Because many people are greedy and if the won some, they want to play futher.
And that will be really bad because they will lose more money than you win money and that is bad.
