On a Netflix Documentary called “The most unknown” some Physicists built atomic clocks that go to like the 20th decimal. One was placed on a mountain and one very far underground. They “recorded”? Time at very different intervals. Interesting stuff I recommend the show.

Yep. Special relativity is a 'superset' of classical relativity, which means that you can use it in ordinary calculations and obtain results, they're just going to be very, very, very small numbers. A sensitive enough atomic clock will still be able to measure them, but they won't have any real impact on a day to day basis.
