Yes, that is true. 'Light and Matter' become 'mass-energy' inside a black hole, and can exit via Hawking Radiation. This comes out at a specific rate which is related to the total mass of the black hole. However this 'leakage' is very slow, and in a stellar-mass black hole, the amount of leakage is actually slower than the amount of mass-energy the black hole gains from the universe. So stellar mass black holes actually get bigger, rather than shrinking. Eventually, in the far distant future when the universe is colder than it is now, this flow will become reversed, and stellar mass black holes will evaporate.Unless maybe things as we know them to be (i.e. 'light' & 'matter') are changed somehow into something else, which might be able to exit in a different form?
A stellar mass black hole will evaporate in about 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 years.
