But Sir most of the people are here who are playing gambling only for making profit not playing for fun. But you are right. i also want to explain, if we use the gambling as a game than we know about the lose or win, because every game has lose or win, so it doesn't take matter what we lose, but when we win we will be happy.
If you really treat gambling as an entertainment then whether you lose of win that should not affect your life. The worst thing is when you gamble for profit but you do not have the required bankroll to gain some then you are just playing in gambling relying on your luck with your little resources to grow in significant value.
