ELI5: Why is it hundreds of stars at night can be seen from Earth, but videos/picturs of astronauts in orbit never have stars in the background (it is just black)?

It's about exposure.

A photo from Earth at night looking up has probably nothing in the frame other than stars.  This means the camera can keep the shutter open for a longer period like 10 seconds, allowing dim objects like stars to be visible.

Videos and pictures of astronauts have an astronaut in the foreground.  The camera is exposing for the astronaut, probably at a shutter speed of around 1/200th of a second.  This is too short to see any stars except maybe the very brightest few.
