I agree with the above comment. 10,000 hours doesn't improve anything if there's no plan. There are so many players who have over 10,000 games on Chess.com or Lichess but aren't even 1500 rated. However, if there's a plan for learning, playing longer time games & analysis of mistakes. There would be a good chance that person would be an expert after 10,000 hours.
10,000 Hours

This obviously doesn't include studying, puzzles, or other forms of practice; but how many estimated hours do you have in chess? And what rating are you?
