That is certainly true, but if their grandiose claims are true, it still doesn't explain why they don't spend more of their free time gambling. I mean, I'm having a beer or coffee with someone who claims to be able to earn so much from gambling that, if true, this means that he's paying the opportunity cost of hundreds of dollars an hour for the pleasure of wasting time here with me and my friends instead of going gambling. That just makes no sense at all.
