Depends on what the keywords are. Since you don't really care about the site, I'd guess that they aren't keywords that are going to make anyone a lot of money. In general, that means they aren't very competitive -- the people who are best at getting good rankings are doing it where there's money to be made.
100,000 results, for that matter, isn't very many ("web hosting" for example brings up 104 million results at MSN -- and 811 million at Google, "home mortgage" brings up over 16 million, and "online casino" 35 million). That's another indication that it's probably not a very profitable query.
