Answer to your ?: In humans, the navel scar can appear as a depression ("innie) or as a protrusion ("outie"). About 90% of humans have innies. An "outie" navel is caused by the extra scar tissue left from the umbilical cord or from umbilical hernias. Umbilical hernias happen when the abdominal wall muscles don't close completely. This is not a concern & they eventually close on their own by age 3-4 yrs old.

Innie vs. Outie: If the belly button protrudes it's an outit, if it's sunken it's an innie

Is there any difference if you have an innie / outie belly button? Does it matter?

No difference: Innies don't live any better or longer than outies. There is probably some web site dedicated to their respective cause, but to most it just doesn't matter.
