It's falling pretty quickly, down to about ~60% of male infants as of 2022. General prevalence is higher (because that's how decreasing rates work), somewhere around 80%, but I'd suspect it's highly regional.
Common, but a lot of people never get it. Either they didn't grow wisdom teeth at all, or they aren't pressing into the rest of the teeth in a way to cause a problem, or they lack dental insurance.
It's one of those super low-priority surgeries for most people. I'm very glad I got it done myself, though!
