I don't know the best gambling movies because I am not too often watch gambling movies. But I watch Ocean Eleven, Casino Royale, and the other film that is related to gambling games that I think is a good movie. I don't watch the list of gambling movies that @OP mentions, so I don't know which one is the best gambling movie. That list is too old for me, so I think I prefer to choose the other films that are not too old from those listed. Perhaps, from that list, there are one or two movies based on the true story from the real player who can win much money and be willing to share his experience in that movie.
I already watch ocean elecven and it is nice movie, I forgot some of the gambling movies that I watched before.
If the movies is gambling related is either they will going show their strategy and about cheating the theme of the movie.
Op list gambling movies is I think is old movies and Im looking for some new now or the movies happens last few years ago because I really like to watch some movies like that. What is the title that you watched movies about true gambling story can you share with us so we can watch it also.
