Yes, and I explained why his question (as opposed to, say, 'vs whom will Magnus earn 0.85 points per game?') leads to even more complications because the Elo / FIDE formula is too crude (based on points, not separate win and draw counts)
Once again, I believe there's no definitive answer to his question, except that a player rated 700+ points lower is almost guaranteed to score <0.01 points per game and hence automatically win less than 1% of games, but this estimate is too nitty because draws happen. A very aggro 2250 CM might as well win 2% of games with Carlsen (while losing all the rest), while an extremely Karpovian 2600 GM might win less than 1% but draw 40%.
Also, the time control matters a lot (there are way fewer draws in bullet than classical chess ldo, and Magnus is more likely to simply blunder a random mate in bullet).
