For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
The object swallowed by the black hole is destroyed; its mass is added to the mass of the black hole.
There is no "average" mass for black holes throughout the entire universe. Black holes range greatly in mass, depending on how they were formed, and how long they have existed if you take Hawking Radiation into account. Mass can be anywhere between a couple hundred protons, such as those created by cosmic rays striking Earth's atmosphere, or an enormous mass such as those in the center of almost every spiral galaxy.
