Abstractions only _really_ exist in your mind as all abstractions (at least in software) are implemented with the lower level of that abstraction (which itself is an abstraction and so on) So it could be argued that the abstraction isn’t _actually_ different than the sum of its lower level parts. It’s your understanding as a human (potentially and probably shaped by your society) that makes the abstraction easier to understand than the lower level bits. A shared understanding (at least between an author of an abstraction and the lower level components it’s built from) is required for a software author to make any abstractions anyway.
