About ELO Rating

Is there an ELO rating for approximate range of player skill levels now? It does not have to be so convincing and trustworthy as you may have required yourselves to be, but just an inaccurate comparison table is good enough. For example, a new player may be rated at 0 ELO, a player who can get to 9000 trophy may be rated at, say, 800 ELO?( So his win rate against a new player would be about 99.01%), and a player who can get classic challenge 12 wins may be rated at, say, 1600 ELO (same reason), a player who can get grand challenge 12 wins may be rated at, like, 2000 ELO (90.9% winrate against the former level), and a more detailed table as to FoL rating (at the end of the season, of course. Plus, you probably need to differentiate between a long season to a short season.) to ELO rating, e.g.(long season finishing) 2000 FoL to about 2400 ELO, 2400 FoL to about 2600 ELO, and so on, till you get the list up to Mohamed Light, the GOAT of CR, probably at 4000-4400 ELO.
Just out of curiosity.

By the way, how do you take the deck matchup into consideration when you calculate the winrate of a game given the decks and ELO rating of the two players? There’s got to be a mathematically-grounded patch to the good old formula 1/(1+exp(D/400)) right?
