No. Are they actively saying that demons won't be a race? No, there's no need. That's the whole basis behind concept.
They also can't backtrack their lore. Let me explain - Viera are not a single gender consisting of only females. They are not like Hyrule's Gerudo (1 male every 100 years versus 1 or 2 males per every 10?) . Viera have males - they live annexed from the more "social-able" female Viera and are basically exiled from contact from everything to guard their homes.
