Could an astronaut or satellite fall into a black hole that we didn't know about? (Beginner)

Do scientists and astronomers know exactly where each black hole is or is it possible for satellites or astronauts to be pulled into a black hole that was not known?

We would be able to tell if a black hole came close enough to the Earth that satellites or astronauts could fall into it as a black hole that close would severely disrupt the orbits of the planets! It is not thought that this is likely to happen. Black holes seem quite rare, so the chance of there being one anywhere near us is very small. Space is very big.
