Yes, they can, so far as we know you gotta think of a black hole as a giant pile of dirt, rather than a hole. There is no limit to how big a pile of dirt can get.

They will just get more and more massive over time, and one theory is that is how the universe will “end”, with all matter and energy being absorbed into black holes.
