I think most casino players follow the standard hand rankings in poker when playing games like Texas Hold’em, Omaha, Seven-Card Stud, and other popular variants. The rules and rankings are established by the Poker Hand Rankings chart and are considered to be a universal standard in the game of poker. However, it is important to note that some variations of poker may have slightly different rules or hand rankings, so it is always recommended to familiarize oneself with the specific rules of the game before playing.
