I earned nothing from gambling. I just gamble for fun. The lost money is very small amount, so does not affect my life.
losing isnt really fun now is it 
gambling cannot make enough money to earn a living.
if that were true, professional gamblers wouldn't exist. professional means you do that job or activity for a living. gambling cannot make enough money to earn a living.
yeah I agree, because this will be your burden to always win. but if only to have fun so it would be good
