You can "demote" up to 100 URLs that you do not want to appear in sitelinks.

This isn't a straightforward list of 100 URLs. No. You have to specify which "search result" you want to demote the URL for.

I guess this means that you cannot completely block any particular URL from appearing in sitelinks.

The example is for a search result of "www.example.com/" but what other search results actually show sitelinks?
