Wrong. Hawking radiation (which is rather plausible, albeit obviously difficult to test) dictates that black holes can lose matter. For example, a black hole of the mass of the moon and in its location would more or less break even; it would absorb space dust, the occasional larger object, and cosmic radiation, and radiate a roughly equal amount of energy.
I actually knew that! I've forgotten most of the stuff I read about black holes, it's ages ago. Maybe I should re-read.
