Why do girls younger than me have breasts?

I just find it hard to believe that most 18,19,20 year old chicks (women) have natural boobs. As a dude (man) I have a flat chest. I see all these cuties on TikTok and Instagram and Facebook, and I see the balloons all the time, and their cleavage most of the time.

Girls' boobs start to grow from the start of her puberty, like at the age of 12 - 13, since then they only grow and change more and more since there are many factors who can change them.
