Not necessarily. There's people whose wisdom teeth never come out. My mother never got them, and I'm 34 and never got the pains nor the teeth UzuHanabi
All of mine came in at the same time at age 24, but I think the normal time to get them is between 18-25 Teiler
I got my wisdom teeth out when I was 14 years old. It wasn't bad for me. It wasn't an op where I am unconscious or something like that. They just numbed the area of the tooth etc.
but srsly wisdom teeth is so scary ╥﹏╥
