My point was that being within the "habitable zone" does nothing to increase the "chances" that the planet is suitable for a biosphere.

Gravitationally induced heat, or the local star(s) are far from the only sources of heat or energy. And we're still learning the subtleties of Earth's energy economy.
What about radioactive decay?
