Each game involves a different number of hole cards distributed to players. In Texas Hold'em, participants receive two cards, while players in Omaha are dealt four. This difference makes it considerably easier to form strong hands and straights in Omaha.
Both poker types ultimately create a five-card hand made up of a combination of community and hole cards. However, the method in which players utilize their hole cards differs significantly in each game to form their five-card hand.
In Texas Hold'em, players have the flexibility to use both hole cards, just one, or none at all to create their hand. On the other hand, Omaha requires that players use exactly two of their four hole cards.
