it does, but it orbits the barycenter (usually the supermassive blackhole of the host galaxy), but since it can pass through itself its orbital energy doesn't decrease from "drag" as it's falling through itself and normal matter
At this point my knowledge probably pales in comparison to skimming some Wikipedia articles, but my understanding is that there is just so much dark matter concentrated in these halos and inter-galactic structures of it that the gravitational effects of baryonic matter are negligible in comparison.
I believe dark matter comprises something like 80-85% of all matter in the universe.
