Usain Bolt is a good example. He had good genes from a young age (1.96m at 15), then made the national junior team where he had the opportunity to train professionally and be singled out by the government as the most promising rising star, with special attention and resources to allow him to develop. Then he worked his way to a world champion. So it's exactly the same luck - nurture - dedication pattern. Of course, genes are how luck manifests for athletes, while knowing a radio DJ might be the singer's chance. It still doesn't mean there was anything magical about Bolt or his training regime, or that his rise to 'greatness' was pre-ordained. He didn't have 'great' genes, he had good genes and he did everything right, avoided accidents etc. Just like other athletes, but his unique genes-training combination turn out to be the lucky one.
