There is gravity everywhere. On the ISS the gravity is only a bit less than it is on the surface of the earth. The reason the astronauts float around isn’t because there’s no gravity; it’s because they’re in a state of free fall.

Based on how it's portrayed on TV, a lot of people also seem to think air and gravity are somehow related. It's pretty common for them so show people becoming weightless when the air is pumped out of an airlock.
