What determines if one has an innie or outie belly button? Genetics? How the doctor ties the umbilical cord? How it heals and falls off?

google says:
“Most people who have an “outie” fall into one of two categories: either they were born with a tiny umbilical hernia, which is most likely, or had a small infection at the base of the umbilical cord that went unnoticed. This will cause unusual tissue called granulation tissue to form.”
aka genetics and luck (or unlucky based on how you see outies)

chance of being an outie is 1/10 as other peeps mentioned
