Casinos certainly know if you consistently win. It won’t matter to them if you are just lucky or are a card counter, if you win more than they think that you should they will ban you.
That’s one more reason not to believe the idea that Paddock got rich by gambling.
Like you, I think gambling is how he was laundering money. That, and his real estate investing. Both involve large sums of money that may not attract attention if you report large taxable gains.
His dad was a career criminal. Stephen just put into practice a few tricks he learned about how to stay invisible to the authorities.
“....if you win more than they think that you should they will ban you.”
I think you have it all backwards - win millions of dollars a year from a casino like Paddock did, and they comp you all the nice rooms and stuff so you’ll keep coming back to win even more money from them! /s
Hmm - His burger, soup, bagel and two Pepsi for $48 - no wonder they can afford to comp him a room! (Anybody know - meals aren’t comped I guess?)
