Read the OP again.

Are the ratings of people who have never played chess games on this site (default rating is 1200) factored in when calculating daily ranks?

EO__ asks about how the daily rankings are constructed and whether the non-playing members are factored in (default rating 1200 {there's your confusion}).

On topic:
It appears as if the ranking system only has 309,000 elements, whereas the site has more than 2,000,000 signed up. I think those figures make it fairly clear that all sorts of subsets are not included in the final calculation. I would hazard a guess that the set of "all those members who have never played a game" is not counted.

Look through this list until you are satisified nobody has zero games played.

Now look through this list http://www.chess.com/echess/players.html?name=&country=&min_rating=&max_rating=900
You will find these players and many others with one game played.
