Ever wondered why something is called a catch 22? Well, I did. And I researched it for you!
A man named Joseph Heller wrote a book that was published in 1961 about said phenomenon & coined the phrase "catch 22". He initially wrote about war, government and other heavy things and realized the satire in that some things were "heads - I win, tails - you lose"; hereby "catch 22" was created. So really, it's just a phrase made up by a dude. However, the number 22 doesn't actually have any significance! He wanted it to be called a "catch 18" but there was already another book at that time with the number 18 in the title so he settled on 22 for the appealing sound of it.
"In short, Catch-22 is "heads I win, tails you lose." If you can, you can't, and if you can't, you can. Fair is foul and foul is fair. Whenever you try to behave sensibly in a crazy world, there's a catch"
