Everybody on chess.com is overrated aprox 300 compared with FIDE ratings. So the boots should be to. You can't compare different rating systems/pools.
Boots ratings may vary more than humans, as it is still very difficult to make boots play bad in a realistic way.
I heard that bots on chess.com are overrated by several hundred points, so for example, Antonio bot who is rated 1500 is realistically probably rated 1200 or so according to the general consensus.
