Even if I had unlimited money, I'd likely still gamble, but the goal would be simply to have fun, fill my free time, and relieve boredom. Even in the current situation, gambling is primarily for entertainment, with the occasional small hope of winning. But when I have unlimited money, I won't just gamble; I'll definitely do other things for fun too.
I can't imagine a successful life with unlimited money. I'd likely do anything for the entertainment I desire.
