Well your expectations seem realistic unlike the characters who seem to expect to make a living by putting adense on a site that gets daily traffic barely out of single figures.
A lot will depend on how well targeted the ads are to your visitors, as opposed to being targeted to the keywords on your site. By way of example I have a local music site. G targeted ads on the venues page to the locations so ads there ended up being for local plumbers and builders which didn't get clicked. The gig listings got ads for festivals, clubs and performers which a few visitors actually clicked on.
I would say that it was worth trialling but probably not worth the effort of tweaking the site if G doesn't serve the ads that you need.
