It's neither an admission nor a denial. But I get your perspective on it being funny, and it is. Just like there's data in there on UFOs and aliens even tho CIA doesn't officially confirm those.
I think the FOIA reading room is basically like a library of interesting things. I'm surprised more people don't see the value of the stuff in that library. It's one of the best digital collections online, I think. And the search through scanned PDFs is pretty great...I suppose you can expect that from an intelligence agency.
