That's because you define atheist to include all agnostics.

Not at all. I know many agnostic theists. But they don't
self-identify
as "agnostic".

Why don't they do that?

Because most don't really understand what it means to be agnostic, and
the word itself is quite ambiguous in meaning. Most theists think
"theist" is sufficient to represent their worldview, without
qualification.
