black holes can also be small, actually, it's based on a ratio of mass to diameter

You only need a high enough density of mass to form a black hole. You could take any amount of mass and in theory squeeze it hard enough to produce a black hole.

The sun is not massive enough for the astrophysical processes to form a black hole, but if you squeezed the sun into a small enough space by some magic it you could form them.
