It is not old enough. It is estimated that it would take trillions of years for a white dwarf to a black dwarf. The universe is only about 13.8 billion years old.

Are dwarf stars black holes?
no, dwarf stars don't have enough mass
Why do some stars die out as neutron stars while others die out as black holes and white dwarfs?
It won't turn direclty into a black dwarf. Some stars will turn into a white dwarf; when the white dwarf cools down (it no longer produces energy), it will become a black dwarf. It is not likely that there are black dwarves yet, since the Universe isn't old enough; this is an expected future stage in the development of some stars. and be cause yolo
What is the age of black dwarf?
It varies widely. Most black holes are believed to form when massive stars die. These very large stars generally last only a few million years and likely have been forming and dying since the formation of the first stars about 13 billion years ago. It is estimated that such a star dies every few seconds in the observable universe. Therefore black holes likely have a fairly even distribution of ages ranging from newly formed to nearly the age of the universe.
What do white dwarf stars become?
Black dwarfs. [See related question]
Why is a black hole considered an oddity in the universe?
Considering the other oddity's in the Universe; Neutron stars, pulsars, Wolf Rayet stars, magnetar or even hypernovas, I don't think black holes are that odd.
Are there any black dwarf stars?
No. It is estimated that it would take trillions of years for a white dwarf to cool to a black dwarf. The universe is not old enough for that to have happened yet.
Are dwarf stars black holes?
no, dwarf stars don't have enough mass
Is a dead star the some as a black dwarf?
No, a dead star is different from a black dwarf. A black dwarf is a type of stellar remnant, but not all stars become black dwarfs. When a star dies it will leave behind a white dwarf, a neutron star, or a black dwarf as a remnant depending on its mass. Given enough time a white dwarf will eventually cool to a black dwarf. The universe is not old enough for this cooling to have happened yet.
Do some dwarf galaxies contain 1 billion stars?
Yes. Some dwarf galaxies contain at least 1 billion stars.
Do Dwarf galaxies contain only dwarf stars?
Dwarf galaxies merely refer to the size of the galaxy itself, not the stars in the galaxy, so no.
What do stars do when they get old?
Some stars become a black hole or a black dwarf.
Where is the Red Dwarf Star?
There are many red dwarf stars in the universe. They are not most common type of star.
Are Stars going to die soon?
By "die", you probably mean explode in a supernova, turn into a black hole, or turn into a white dwarf. According to The Universe, one supernova is predicted for about every second somewhere in the Universe. This means that stars are always constantly "dying" in the Universe.
How many stars does an average dwarf galaxy contain?
An average dwarf galaxy contains few as ten million (107) stars.
Is it a dwarf galaxy since it contains 1 billion stars?
Yes. Some dwarf galaxies do contain 1 billion stars.
Do galaxies typically contain between one million and ten million stars?
A dwarf galaxy might contain this number of stars. A galaxy will contain billions of stars.
Is the sun or a black dwarf hotter?
stars
