Only if you dont exceed your limits.
You can gamble and win or lose, but dont do it too much, even if you win a lot, because luck can change anytime.
That should be correct. If one know what is doing and how much his/her limit to lose on a given day then their shouldn't any issue in gambling because it is some kind of entertainment for some people but if this entertainment become a full time job then it will be wrong for every one. So just gamble to pass the time some times should be fine.
