The “profession” of gambler had to be a fake. The casinos wined him and dined him and gave him freebies they only give to big repetitive losers. Consistent winners get limited or banned from the premises.
The only way I know of that someone can consistently beat LV is through card counting. And, if someone won 10-15 thousand $ a couple of times, they would be banned from the casino, no questions asked. Card counting is not illegal, but the casino is private property and the successful counter would be asked to stay away. So, the "professional gambler making $5 million in a year" story is a phony one.
How can the media people be so stupid and gullible to believe this story, and pass it on as credible news? They just accept what the authorities tell them?
