The coinjoin rabbit hole goes really deep, I'm still learning new technical nuances constantly.

To get a rough intuition of the privacy properties, I think it's best to look at a WabiSabi coinjoin and ask yourself these three questions:

Which inputs belong to the same user?

Which outputs belong to the same user?

How many users are there?
