Club calf is just a catch all for any calf that is sold for the showring. Could be a crossbred or purebred. Anymore, a lot of them are AI or ET calves out of a handful of bulls. Some of the "name" bulls are Who Made Who, Friction, Heatseeker, Heat Wave, etc. Some times people who raise cattle in general, throw a club calf label on their steers and double or triple the price. Newbies don't know any better. Ask the breeder how long they've been breeding for the show ring, and past successes. Takes a while to build up a good base of breeding stock.
