I for one am shocked that such sarcasm even exists, in the forum of all places! OMG, what will happen next? I suppose it’s Christmas and a fat jolly man in a red suit will come down my chimney?! Wait, I don’t have a chimney. 

bruh even i with some lowly rating got 90 plus rating in some games, i don't even know about engines properly 

If you want to see how hard it is to get 90%, go play some games against the very weakest bots that chess.com has to offer, and do the analysis after (assuming you're a member).  Even against terrible players, it's hard to get that kind of accuracy.  

Depends on which one I just tested this on my phone martin falls for my opening trap loses in 16 moves  blundering 5 moves in a row 98% caps

Then I tried Fabian while I annihilated him I didn't know the best moves vs his random flank pawn attacks and only got 80% sad day
