In theory. We actually don't know as we can't actually measure whether they are or not.

Well, since they have mass they are a source of gravity. However, compared to the other forces (normally) operating at that small scale, gravititational effects are practically zero. Now if we are talking about the very tiny region inside a black hole, the "singularity", then things are likely very much different. There you have an immense gravitational field at the atomic/quantum scale. Weird things surely must be going on there.
