I don't see any proof from your post, just because you see the dealer, wheel, dice and cash, it doesn't mean they're legit.
If you play roulette, you need to know whether the machine is not getting controlled by someone or not. If you play slots, you also need to know how the machine work and it's transparency.
Online casinos are better because they give information about the games and they also show the RTP rate, we can make research about which providers are legit because many gamblers had share their experience.
