Yep. I had a neighbor growing up that got all the coaching, was a great player and did well as a doubles player- but he had exactly one good run in a major tournament at singles- quarterfinals at Wimbledon. He didn't have that next level of extreme athleticism- he could make every shot and was very proficient and earned a good living on tour, but if he hadn't come from good money he never would have been there in the first place, because he didn't have the native talent, never getting into the 60s in ATP rankings. Doing great as a coach though.
