Learn to Race?

Sort of...

Riding on the track necessarily uses racing skills. Every skill you use in a track session is applicable directly to racing. In fact you can develop your racing skills better in track sessions than you can by actually racing. In the same way that the absence of SUVs lets the street rider concentrate on technique, the absence of competition lets the race rider concentrate.

...but not exactly

Racing is not just about riding fast. It's very important, of course, but there's a lot more to racing than just going fast. Oddly enough, passing is a very small part of racing. The time spent passing is dwarfed by the time spent riding alone or in a constant order. Now riding fast in a race does involve dealing with slower traffic -- getting through backmarkers can make an enormous difference in lap times -- and the ability to adapt your lines on the fly is something that's difficult to practice in a regular track session. There are also factors such as the very critical start procedure, race strategy and tactics, and end-race strategy and tactics.
But racing also involves dealing with the sanctioning body, licensing procedures, bike preparation, at-track modifications and repairs, entries, protests, medical requirements, and staying friendly to more officials than you'd meet in the Pentagon. It's not just dealing with all that, but being able to stay focussed and leave it all behind once you hit the track.

So while track sessions do give you the techniques and skills you need for racing, there's a whole other mental and theoretical field that you need to master to be a consistent winner. You can race and win the occasional race by just being fast; you can't win a championship that way.
