A standard deck of 52 unique cards can be arranged in 52! (52 factorial) different orders.

That's:80,658,175,170,943,878,571,660,636,856,403,766,975,289,505,440,883,277,824,000,000,000,000

Or roughly 8.0658 × 10⁶⁷

I would say the laws of randomness say this isn't true. There have been billions of decks of cards shuffled over hundreds of years. There is just no way possible that no two decks have ever ended up in the same order.

However, Grok has explained to me in great detail that I am wrong. Its actually quite mind blowing.

TIL, eh?

I didn't believe it at first either.
