That's because Las Vegas is actually fair to the extreme. The odds are in place, they are what they are, and if you hit the lucky number, you win all the golds. There's no deception at all, except for that people enforce on themselves when they go there expecting to be that lucky winner.
As a simple example, slot machines are actually implemented as raffle tickets, not mechanical random generators. But not losing plays are deceptively displayed as being "almost" winners. You get a "star star (half star, half bar)" far more often than if the machine behaved the way it appeared.
Then of course you have free alcohol during bad decisions, no clocks, upsells for crap like "insurance" at blackjack....
Not impossible, but you do have to do some brazen, easily-detected stuff like watch the table for awhile and refuse to sit down unless the count goes positive.
