Suppose, as title says — you had infinite amount of money, would you still gamble?
If the situation were the same, I'd probably still gamble. The truth is, we gamble to win money, but with the length of time I've been gambling, I'm not sure I could just stop betting even if I had a substantial amount of money. It's also possible that some gamblers with large capital aren't just chasing wins and multiplying their money. There's a thrill they naturally seek from gambling.
