The point about 10,000 hours is that anyone can become good.

The point of Outliers, the Gladwell book, is to dismiss the idea that talent exists at all. "A person with sufficient talent", as you say, is a person who started onto decent amounts of practise at a young age, such that by the time the world notices them at age 8, 10 or 14, they're already surprisingly good and can make good use of professional coaching.
