Yes. I know personally I have never clicked on an ad in gmail. They're always for totally bizarre things. For example, the last Fandango email I got served up a bunch of ads for roofing companies. See Alice in Wonderland and get my crawl space sealed! I guess... Anyhow, Google wouldn't lose one red cent if I covered those ads up since they make money on a CPC (vs. CPM) basis.
