There are a lot of issues around notability, not least of all the availability of third party sources which varies by a ton of things including pre-and post- internet notability. But also the nature of their or its notability. On the one hand, you likely have articles on fairly minor actors and pro athletes and you probably don't have articles on many tenured professors at major universities even though they're pretty much by definition notable in their fields--but there may not have been much written about them as a person.
