Perhaps it helps to see it this way:

1. CAR and CDR (in upper case) are the two halves of a cell

      +-----+-----+
      | CAR | CDR |
      +-----+-----+

   no matter whether this cell represents a number, a symbol or a list.


2. 'car' and 'cdr' (in lower case) are the functions to access the
   elements of pairs and lists.
