Wisdom teeth fully formed at 16, defect?

[berseker]

I’m 16 years old, today I talked to a friend, he’s 18, he complained that wisdom teeth had started to erupt, I joked that he was defective, he told me that this is the norm, after looking on the Internet I saw that wisdom teeth appear on average at 25 years old, I had all 4 wisdom teeth appear and fully erupt at 16, is this a defect? they don't bring me any discomfort

No wisdom teeth don’t have a certain age of eruption,same thing with children who loose they’re baby teeth and grow permanent teeth.
I lost all my baby teeth and got all my permanent teeth when I was 9 while people who I knew still had a couple baby teeth at 12
