It's impossible to gauge anything from accuracy here because accuracy scores are graded on a curve. If you are lower rated, it is less stringent with the requirements for a good move. You and Magnus could make the same move in the exact same opening and it will call it a mistake for him and a great move for you. And there are varying levels of that all the way from beginner to world champion.
