> A selector is not not a variable or a function. CSS has functions (e.g translate) and it has variables, which are both distinct concepts in the language from selectors.

That misses the point. They're identifiers scoped to the entire document - the same way global variables and global functions are identifiers scoped to an entire program.

The point is, comparing CSS selectors to the functions or variables in other programming languages is silly, cause guess what... CSS actually has functions and variables!

I am sorry that you are bad at analogies.
