....if the parked-domain page has no content except AdSense, the odds that a click will result in a sale aren't especially good...

When I said small sites with adsense (even 1-pagers) are likely good for the advertisers of course it was meant assuming they had some relevant content and a keyword rich domain name identifies the subject.

Sure ad only developed sites are not good and also violate the Adsense TOS anyway. However, with small sites and parked domains, if the title, domain name, description and possible old bookmarks and old links bring traffic and are relevant and the url may be ranked in the SE too, then that traffic likely performs and converts well as it is considered to be targeted.
