Yes! I believe this movie is based on real story since there’s a real life event of group of student beat a casino by just playing blackjack. This is really possible back then when casino is still not using multiple decks and frequent shuffle method to make counting impossible but right now there’s no working trick to beat the current version of blackjack.

Using the basic matrix table for blackjack will help you play with minimal house edge but still not enough to win the game consistently like what the movie did.
