As you have indicated, black holes form when very large stars run out of fuel and are no longer able to mauintain pressure to overcome gravity. To become a black hole the star must be large enough so that gravity can overcome other forces which constrain collapse, such as electron pressure (if smaller, it only collapses to a white dwarf). If the elctron pressure is overcome it becomes a neutron star. If the neutron star is large enough so that the star's radius is less than a critical radius, it is a black hole.
