Nothing wrong if you're winning. Losing on the other hand, now that is so wrong especially if the money you gambled with is a hard earned money. Better stay safe and don't gamble.
It's not wrong to gamble your hard earned money because whatever we call it it's still money that has the same value regardless on how you get it, what's very important is we gamble with discipline so we will be able to spend only what we can afford to lose.
The problem will only happen once a gambler loses control and spend outside his budget, normally it will bring stress that will affect your mood and you will not be productive anymore.
people consider gambling as wrong for the only reason that most of the people do not play gambling in a right way, they do not have limit for gambling which increases the chances of losing money, therefore people call it as wrong and not as a good way of earning money. but i think that if a person ahve limit and he play gambling in a right way with a good limit then gambling is not wrong way of earning money. i thin gambling is smart if a person play gambling in a limit.
