Rounders is a great movie but its all about cards as I remember, very well done of course its the one to watch for a more accurate portrayal. ~
I watched it yesterday, and indeed the whole movie revolves around poker, and the main idea, imo, is that you will go nowhere with cheating. Instead of learning how to cheat, you can learn how to
play watching the games of the top poker players, just like the protagonist watching 1988 World Series of Poker Main Event on video tapes(something that is much easier to do now using YouTube).
So, in response to the OP's question
~
Or do you have some other gambling-related movies you’d also suggest others to watch?

I'd say, Rounders(1998) is definitely worth watching.
