How low rated players can score 30+ in Puzzle Battle and beat much stronger players?

I play in puzzle battle time to time and solve 27-28 puzzles(maximum was 30) in 3 minutes portion. and players who have 1300-1500 blitz & rapid & bullet ratings do solve more than 30 puzzles in 3 minutes and beat me all the time. and my ratings in chess.com is above 2000. how is that possible? am i really that bad finding puzzles or is it because regular players already memorised so many puzzle patterns to solve quicker?

Some players are more "gifted" in the area of puzzle alone. Also, the first few puzzles in most Puzzle Battles are the more obvious ones such as one-move mate or back-rank mate.

For me, I would actually expect a 2000+ rated player to obtain around 35 in Puzzle Battle and 60+ in unlimited-time Puzzle Rush.

I just played a 943 rated player and they did 28 puzzles in that time, Im not sure if they cheated but I felt bad cuz that was the first time I got over 23 right

This happens to me all the time

Some of them have many accounts so they can play for free on a daily basis, so their account's rating might not be accurate
