Nowadays, when people refer to "dark matter", they mostly mean stuff which just plain can't interact significantly with light, not just stuff which can interact but happens not to be. This is the 22% you're referring to. More properly, it ought to be called "non-baryonic dark matter", but what can you do?

It's been known for quite a while that there's baryonic matter out there that we can't easily see, but that's not very exciting, so the exotic stuff gets all the press.
