On: Signatures of gravitational atoms from black hole ...

[treis]

Why wouldn't the primordial black holes condense into bigger ones like the matter that makes up planets and stars did?

[itishappy → treis]

Some would, but the vast majority of matter is not found in planets and stars. Most stuff just floats around on it's own out there.

[kadoban → treis]

Some of them would, some wouldn't, depends on where they were and how they were moving.

This is a bit like asking why Jupiter isn't part of the Sun but other stuff is.
