Of course, but there are still four schools which are clearly the "top" ones. The same is true for academic conferences, or big tech, or intelligence agencies.
Top is just marketing. In Big Tech it's market cap or something, but it's not proof of anything and may be just marketing. Google is a search advertising monopoly pretending to be a "tech" company (per Thiel), but is a "top" company to work for. Ok.
And intelligence agencies are government mandated, not marketing made. Or at least I haven't heard any marketing from the NSA saying how selective they are in admissions (as if that means anything).
