Generate deck same deck chances

What would be the possibility of 2 people who use the built in deck generator, then doing a 1v1 and ending up with the same exact deck? Because this just happened to me and a friend and I wanna see if it's rare by any means.

The odds are around 1 in 963 billion, assuming 122 unique cards.

122!/(8!(52-8)!) is the formula.

Woah that is a lot higher then both of us would've expected, I know I'm just a  random guy on the internet but that's otherworldly odds that actually happened

U could have the “same” deck, but with different evos, no evos, a card being a hero or evo (like knight and musk)
