Its differ from everyone's perspective. For me, it's not wrong for gambling because I treated gambling is a very risky investment. You place money to get more money not very different from nowadays investment, but very risky win big lose big.
I don't understand this what the wrong way is in gambling? And what is the right way in gambling? According to me, Gambling is just game. How you treat gambling is the matter. If you play this for money, then it is wrong. But if you play gambling just for fun or entertainment then it is ok. Finally playing or not it depends on you.
Yes it depends on players. player itself decides if they are playing for entertainment or not. its just a game and if you become addicted and had debts because of gambling, it is because you have no control and you are playing without limitation.
