most of the people consider gambling as fun and in fact they only play gambling for making money, to me gambling can give you pleasure but only if you are making money in gambling.
You are right and those who say that they are having fun in gambling are saying this only till they are getting wins and not losses because once you pick the loosing streak the temper gets high and its almost impossible to stop ourself from gambling and giving more loss. So gambling cant be funny, for sure I agree.
