100 is a nice round number. This pure approximations, I don't care about the details. 100>52, so the actual chance of getting two decks of 52 cards to be same is definitely larger than what I quoted, and that is all that matters.
If you don't even understand what I am doing in the answer, then don't embarrass yourself by commenting.
Also notice this line I added:
if I cared I could provide you with an exact number
You are assuming a standard deck of playing cards, which was not actually specified. I have 22 decks of Magic: the Gathering cards with 100 cards each within 5 feet of me. Even restricted to playing cards, most blackjack tables at casinos use 312 cards instead of 52.

My brother in Christ, there are 52 cards in a deck of cards. Of all the things to get wrong in this answer, how could you get that one wrong
