ELI5: How come the ISS needs regular corrections to it's orbit so it doesn't fall and yet, there are space debris from the sixties that no one is expecting to burn in the atmosphere anytime soon?

1. Debris do fall. But some debris (like Apollo parts) are on very high orbit and are unlikely to fall any time soon.

2. Stuff falls because of atmospheric friction. The higher you are - the less atmosphere is there. The smaller you are - the less surface you have for friction.
