* Formation: White dwarfs are the end stage of the evolution of stars like our Sun. They form when a star exhausts its nuclear fuel and sheds its outer layers, leaving behind a dense, hot core. Black holes, on the other hand, form from the collapse of much more massive stars, at least 3-4 times the mass of the Sun.

* Stellar Mass Distribution: There are many more stars in the mass range that become white dwarfs than those that become black holes. The vast majority of stars in the universe are small, red dwarf stars, which will ultimately become white dwarfs.

* Observed Numbers: While black holes are incredibly dense and powerful, they are also relatively rare compared to white dwarfs. Astronomers have observed many thousands of white dwarfs, but only a few dozen black holes within our own galaxy.

In short: While black holes are fascinating and powerful objects, they are far less common than white dwarfs, which represent the ultimate fate of most stars.
