These are two very different things here, I think. You're talking about celebrity and franchise fandom which is parasocial and exists because they are actively influencing you to become their fan. They're already famous or have made it.

What the article talks about is much more grounded – being excited about other people you know and believing in them. This "fandom" doesn't necessarily originate from admiration of achievements but from sincere belief. You're becoming a fan while they're just being themselves.
