Any Dentists on here or whoever with dental experience?

Ok, so I am 19 years old. I heard many people get their wisdom teeth pulled, like around my age, maybe a little bit older. My mom, she's a dental hygienist and to her it doesn't really seem like I was born with wisdom teeth. Is this possible? or do you think that I'll just get them at an older age. I believed her at first, but now I am kind of like, "hmmmm...maybe I'll get them at a later age". But I don't know at this point. So what do you think?
