I think is possible for all possible combinations of a 52-card deck to occur during a game of Texas Hold'em, then the answer is no. The number of possible combinations of a 52-card deck is astronomically large, estimated to be around 2.6 x 10^64, which is many orders of magnitude larger than the number of atoms in the observable universe. It is therefore highly unlikely for all possible combinations to occur during any practical, finite number of games.
