This is very much my experience. I don't have the 3rd party sites rule enabled because I find it blocks too much, but between known ad sizes and my blacklist:

/ads\..*\.net/
/ads\..*\.com/
/.*\.doubleclick\.net/
/.*\.googlesyndication\.com/
/ads\.telegraph\.co\.uk/
/.*\.facebook\.com/

I hardly see any ads at all. The only time I see ads from google is when I am on google's site, which isn't often since I switched to duckduckgo.
