But when it hasn't sent the file to the user?

Like if the user hits cancel? It's still considered as downloaded.

That'll depend on whether your script has the chance to execute the query which considers it as downloaded.
Unless you're using

PHP Code:

ignore_user_abort(true);

somewhere, your script can be terminated early.
