I dont agree with you. Its true that I loss a lot at first gambling, but sooner this become lesser and at last I recovered my loss now Im still on gambling site playing with it. So all my loss is recovered plus I get some profit again so it is not like you said profit in gambling is less than your loss. It depends on people how they are doing the gambling thing
Gambling is depend on peoples luck, what if that person has 0% percentage of luck! there is not a chance he can manage
to take up all his loss in just 1 day, what if hes not lucky now but will be 90% lucky tomorrow but didn't play that day and
plays the day that his luck meter turns to zero again!? that is why you will never know your luck if you don't try it!
people tend not to try gambling because of experience in the first time they try it!
but in a long run you will never know if you losses or you gain if you not gamble!
