Most people Gamble for profit only! here I'm not an exceptional to this 
if i have enough money to an luxury life i will quit gambling though
yeah getting money wouldn't be a big deal anymore when you have a lot of it already , some people might continue the habit of gambling as they feel comfortable with it / getting a real entertainment there and of course because of gambling addiction itself. but it would easier to leave gambling when you have power or money enough to support it right? if i have enough money to an luxury life i will quit gambling though
