In reality, as a legit player, if you hit a big jackpot or cash out a large amount from playing tables, the casino will just ask you to fill out a W9 for taxes then give you either the cash (plus an escort to your car) or a check (depending on the casino rules) and ask you to come again soon.

A payout rate over 90% is not uncommon in Las Vegas and on the Las Vegas Strip, but there are important caveats to remember. The payouts are across all the machines in a casino and they account for large jackpots.
