Hmmm I wonder whether that is true.
"Good artists copy, great artists steal." - Pablo Picasso
I would contend that you can absolutely be a better designer by learning and education. Some innate natural artistic ability may lift a talented few far above everyone else, but in this day and age you can learn a lot of tricks to take your own talents and use them to full advantage. It can be incredibly difficult for some people to learn in those areas that don't come naturally, but it is still possible.
Few people have the WOW factor. Today we are bombarded by high profile talent published to the web in the blink of an eye, but in our everyday lives few people have need of true WOW factor to earn a living. In terms of getting better at "designing, colour schemes, forms, layout, typography", those are all things that can be learnt and improved.
