You're wrong.

Particularly massive stars will go supernova, with the 'remnant' [what's left of the core] collapsing in on itself from its own immense gravity - without fusion, there's nothing keeping it up, so it becomes an ultradense neutron star.

Even larger stars might instead produce a black hole.

A neutron star, as it gains mass via accretion [the same way a black hole feeds], will shrink and get denser until it eventually implodes into a black hole.

However, black holes can be formed out of energy too, thorugh E=mc^2. Enough  mass-energy in a small enough place will automatically become a black hole.

White dwarves are also 'compact stars' but not to the extent of a neutron star, and are just the cooled corpses of 'smaller' stars like our sun. Black dwarves are white dawrves that have cooled down - and there aren't any in the universe yet because it takes trillions of years. Red dwarf stars don't even become white dwarves, they just cool into black dwarves.

Some really big stars go hypernova instead of supernova, forming a gamma ray burst among other things - sometimes a black hole is formed, other times there's no remnant.
