The claim doesn't even make sense, since she's not comparing women bios with anything at all, much less male bios. Unsurprisingly, when activist editors target people who still don't have bios in 2019, despite at least a decade of diversity drives, you are often going to be scraping the bottom of the barrel.

(Frankly, only 6 out of 700 sounds like they are being treated with kid gloves! Of the several hundred articles I've written or started, way more than that have been deleted or attempted to be deleted, even ones where I can provide literally hundreds of references. A group must be very privileged indeed to have a <1% deletion rate given WP's heavy-handed deletionism these days...)
