Can I still be a good snowboarder if I can't...?

Okay well I can do black Diamonds and every once in a while I can do double black Diamonds on a snowboard. But I can't carve for my life! I'd say I'm a pretty good snowboarder but I still do that beginner thing called the falling leaf.. I can do jumps and stuff too but for some reason I never learned how to carve when I started snowboarding five or six years ago. Does that mean that I'm not as good..? And do you think it's really worth it for me to learn how to carve?
