I'll take advantage to insert a very clear image from Wikipedia (stellar evolution). Black holes evolve out of massive stars and so-called type 2 supernovae events. As explained above, the implosion/collapse of the inner core occurs after the titanic explosion/expulsion of the outer layers. Stars with mass close to that of the sun cannot evolve in black holes, it seems that it is needed at least 2 or 3 sun masses to potentially evolve in a black hole, with the right conditions (the following figure says at least 8 solar masses, but sources can diverge).
