Filmmakers like to adapt reality. Images about casinos are full of inconsistencies with reality. Things happen in them that wouldn't happen in life. How is the imagination different from reality?
All in one card. You know, the players don't want to stretch it out anymore (or rather, there's a minute in the movie for that part), so they all huddle their chips in the middle of the table and let the decision be made now and here! In reality, a casino without limits would probably go out of business. We know this situation, for example, from the movie Maverick, where the filmmakers exacerbated the situation with the following point in Perfect Hands.
Perfect Hands. Old professional players may never in their lives see what Mel Gibson and his colleagues got on their hands - all pokers, full houses and straights. The odds of that are insanely low. In reality, there would be manipulation behind the team, the game would be over and the investigation would begin.
Luxury wardrobe. In the movies, there are players in tuxedos and ladies in beautiful evening gowns. We see it in almost every James Bond. In fact, casinos are mostly in hotels, where the dress code isn't very strict. It's not just billionaires who play in casinos. A few brands are admittedly dress-conscious, but most casinos don't insist on a tie - no one would play in them.
Emotions run high. Inside, players undoubtedly experience all sorts of storms, but showing too much emotion is neither desirable nor part of casino culture. If you were to loudly rejoice or, conversely, lament your fate, you would soon be perceived by those around you as a "naysayer". With such a poker game, a strange notion.
Casino workers will stop you if you win too much. Serial hustlers don't really exist. There are no players who win huge sums on the sequel. Legal casinos don't need to stop players, because there is no such thing as a grounded player - at every round starts over. In addition, casinos return most of their bets to players - and players usually put them back in the game. Why stop there?
Card Counting. Not forbidden, you can count as many cards as you want in your head. It'll just take you a few lifetimes to earn something that way - unless you're a genius (apparently there are a few in the world). This activity was famously parodied in the movie Party in Vegas, where party member Alan wins large sums of dollars twice in succession (the joke is that he's very stupid in everything else).
Fans. In the film, there are several players sitting around a table and behind them a crowd of fans or bystanders who are cheering extra loudly. But something like that is very inappropriate, probably like people standing around the players snookry and cheering them on. In fact, casino security should be fired from their jobs in such a case.
Gangsters. Remember Scorsese's Casino from 1995? He had it starred a real ex-gangster, Frank Cullotta, who really worked for a real boss. This reputation is probably due to early development in Las Vegas. The Italian and Jewish mobsters who divided the city... But in reality, casinos need to look respectable and credible. They have no reason to side with illegal revenue - their profits are high and legal.
