i think it depend on your way of playing gambling, if you have no limit and play gambling with all your investment at one time and every time you faces lost then it is really wrong for you, but if you have a limit and you play gambling up to the limit you can bare then gambling is not wrong for you.
It doesnt matter if you have limit or not because limit doesnt determine gambling is wrong or not. Gambling is some kind of business that they opened for us to entertain us, it is your fault if you loss it so the only thing that wrong is yourselves. By setting some limit I think that is a good way not to lose so much in a day and ot has nothing to do with right or wrong on gambling
Follow the basic principle in gambling which is to have fun all the time, and since we will not be happy if we lose hard then setting a good limit is would be advisable. If we can follow that rules we will never call gambling as wrong.
Gambling are suppose to be fun and it should stay that way, if we deviate to that and aim for money the risk of losing a big amount is there but blaming gambling is not fair as we also have a chance to win.
