Not true. It’s unlikely that even something so seemingly simple as a deck of cards has, or ever will be, randomly shuffled in the same order. Ever.

There are 52! (factorial) possible random ways to order a deck of playing cards. That number is enormous - 8x10^67 (8 followed by 67 zeroes).

If every person on earth (8x10^9 people) shuffled a deck of cards once per second for the lifetime of the universe (4.16x10^27 seconds), no two decks would be the same. This would still be true if you ran the same calculation, but assumed there was an earth with 8 billion people around every star in the entire universe (1x10^24 stars) sitting there for 13.2 billion years shuffling cards every second.
