One reason you don’t see any stars is that the majority of pictures you see from the ISS or the old shuttles were taken whilst on the daylight side of the earth to capitalise on natural light. You may be confused because of the black background to the sky during daylight hours but that is because, here on Earth, light is scattered by our atmosphere making the sky blue. In space, there is no atmosphere so the backdrop of the sky still appears black despite very intense sunlight in the daytime side of the orbit. That’s why you don’t see the stars. They’re still there but drowned by sunlight.
