I am sorry to be so simplistic but these basic things do seem to need answering before you dive into the more rarefied areas.

You're correct. In relativity mass is just another name for energy. That energy can be in the form of matter or antimatter. You can think of throwing antimatter in a matter black hole. The antimatter would annihilate with the matter and turn into photons. Those photons are still just energy (energy is always conserved) and that energy would be trapped in the black hole increasing its mass.
