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 as long as you still have the control on it, and your intention is to gain more fun rather than profit, what went wrong in gambling is that when you let gambling controls you because this will leads you to do miserable betting and always after come to win.
No matter how much control that you have on it, it is still wrong, because you are keep on going even if you know that you are just going to lose all over and over again, and it is like you are not thinking right and ignoring what you must do in order to not to lose your money. It is wrong because you could come up to the point where you will steal someone's money just for you to have something to bet in gambling.
