So the other answers are correct that there are 52! possible deck combinations. From what I understand you're not asking about deck combinations, but rather the chance to get the exact same hand you received before.
For getting the exact same hand while paying respect to suit, for the first card there is a
2/52 chance to get one of the two specified cards out of the 52 card deck and for the second card, since the first card has been already picked and can't be picked again, there is a
1/51 chance to get a specific second card. For both of these to happen simultaneously you multiply them together for a
(2/52) * (1/51) = .07% chance of both specific cards being picked. This is certainly unlikely but definitely possible if you play enough.
What is more likely is that you get the same two unpaired cards if you don't give respect to suit. For this there is a
8/52 chance to get one of the two cards, and a
4/51 chance to get the specific second card. Combined there is a
(8/52) * (4/51) = 1.2% chance of this occurring which would definitely happen with some frequency over hundreds hands. The probability drops a lot if you are calculating the chance to get the same paired hand with there being a
4/52 chance for the first card and a
3/51 chance for the second (since one of the cards you need has already been used.) This gives us a total chance of
(4/52) * (3/51) = .4% chance to get the same paired cards.
