My first thought was that this could affect our estimate of mass in the universe, which would have bearing on questions of antimatter.

but it’s likely a tiny overall difference compared to the black holes at the center of galaxies?

Black holes in the galaxies center tend to only make up a tiny fraction of the whole mass. It's not like our solar system where most mass is caught up in the central body.

The stars orbit the galaxies center not because of the black hole, but mostly due to the mass of all the other stars also swirling around the galaxy. Which from the perspective of a single star is pretty much the same as if all those other suns were part of the black hole.
