Hard disagree. As expertise increases, so does the requirement for deliberate practice. On the two ends of the spectrum, there are those who commit to it, and those who don't. Ultimately, individuals who will reach expertise are those who lean towards a high(er) level of commitment. One can easily observe this in any organized activity. There will be a huge variance in expertise (= skills) among people who have a long experience.
