You’re thinking too Silicon Valley.

These services didn’t need additional rounds of funding and aren't the kind of thing that would scale like a unicorn.

Some services might only been transient (like services based around a particular sports league or TV series) or be regional (like government sites or, also, sports leagues).

Not every service out there has aspirations to “change the world”. Some exist to fill a niche. But sometimes that “niche” still covers millions of people.
