If it were emitting the light, yes, but it's not. It's more complicated than this, but imagine holding a black sphere in front of a light bulb. You'll see a ring of light around the sphere. Somewhat separately, there's the accretion disk, which again is a disk not a sphere, much like other orbiting systems like solar systems or galaxies−the gravity between bodies orbiting the same central gravity source causes them to arrange roughly into a plane, rather than all having their own unrelated orbits. We're not seeing the accretion disk directly though, but rather the light from it, and from other sources, that is able to pass around the black hole. (ie the black sphere in front of the light bulb.) Watch that video; it explains it in a very approachable way.
