Someone on earth vs someone on the ISS have different gravitational experiences for instance.

The experience is different because the person in the ISS is simply not close enough to Earth to be subjected to Earth’s gravity, in any practical amount. But that doesn’t mean gravity stopped existing for them.

Ooh, time for science pedantry! The ISS is plenty close enough to Earth to experience almost the same gravity from the planet as on its surface, which is why it has to be orbiting at such speed - falling sideways fast enough and at the right angle so as not to come crashing down!
