While babysauske is being rude, I think what they mean is that rating players is kinda its own entire industry, separate from watching the game. No one who rates players does so by just watching matches, since you don't even see every player's POV. They look at statistics and a bunch of math. The stats page here on VLR is a good entry to that, but the VLR "rating" stat can also be misleading and not everyone approves of it. This video goes nuts into more complex stats and makes it clear why rating players is hard https://youtu.be/FrLtJSpaSLI
Every one of the players you mentioned is good, and honestly probably more fun to watch than other players. But giving them numerical ratings like that seems odd if other people think you're comparing them to calculated ratings. Many of those players are nowhere near the top 10.
