Gambling is actually not wrong if you gamble only for fun and do not spend to much or play to much. As we all know that all too much would always be not good.
of course it is not wrong at all, in my opinion people can do whatever they want with their money so i doubt that it is such a bad thing
Yes i don't know the real reason behind it but human really find it fun to gamble in some occasion. I myself do the same way especially if you play with your friends or relatives. I think that when person gets addicted to it then that would be the real problem.
