New to Game. Is the race info just fluff and has no outcome in game?

So what the title says. I read in the bios for each race that one is a jack-of-all-trades type and others specialize in certain ares, but in game they all seem to start the same and advance the same. Is that information just fluff and have no real outcome in game? If so, what would be the point of purchasing the advance races but only for the race avatar?

At the moment its just fluff. I hope to implement this soonish.
