ELI5: how can black holes have greater gravitational pull than the stars they're born from?

A super-massive star blows off it's outer layer, and what remains collapses into a black hole.  Shouldn't the black hole then have less mass than the parent star, and therefore less gravitational pull?  Sure, the black hole has extreme density, but gravity is a function of mass and distance.

>gravity is a function of mass and distance.

Exactly, so the black hole has the same (or less, if matter was ejected) gravitational pull at large distances.  The difference is that, at distances where you would be *inside* the original star (and thus experiencing reduced gravity from the outer layers pulling you up), you'll still be far away from the black hole, so the gravitational pull nearby the black hole is higher than anything the original star was capable of.
