If a correct shuffle is done, it's is basically impossible for any card order to have EVER been in that order before.
Basically, no two people have ever shuffled a deck of cards the same way ever, the chances are infinitesimally small.
"The number of possible permutations of 52 cards is '52 factorial' otherwise known as 52! or 52 shriek. This is 52 times 51 times 50 . . . all the way down to one," it says on the QI website.
The number of possible permutations looks like this: 80,658,175,170,943,878,571,660,636,856,4 03,766,
975,289,505,440,883,277,824,000,000,000, 000
