Fun fact: There are more ways to arrange 52 cards than there are atoms on planet earth.

Yes, and by a huge margin:

Mass of earth is 6e24 kg.
32% iron at atomic weight 56 = 1.9e24 kg or 3.4e25 moles
30 % oxygen at atomic weight 16 = 1.8e24 kg = 1.1e26 moles
15 % silicon at atomic weight 28 = 9e23 kg = 3.2e25 moles
14 % sulfur at atomic weight 32 = 8.4e23 kg = 2.6e25 moles
9% misc at around 30 = 5.4e23 kg = 1.8e25 moles
Total = 2.2e26 moles or 1.3e50 atoms

Number of arrangements of 52 cards = 52! = 8e67

Card arrangements = 6e17 times as many atoms at in Earth
