I don't have any story to tell but based on my knowledge gambling most of the brings you loss instead profits. So as long as you avoid gambling then your safe.
Gambling is not wrong because the gamble is based on his own desires and ready to take the risk .. because the gamble victory is only a factor of luck and if it will continue to lose everything .. so gamble that no one forbids the origin of ready to accept defeat or loss.
It is wrong when the money you use on gambling is not your own money or you just lend money from other people. It is not bad to gamble as long as you know how to control yourself and not become addicted to it.
