Yes. Their rating system is different. Everyone starts at 1500 there.
Here, your initial rating is set based on a self assessment. The theory is that your rating will adjust to its proper level
It looks like you started at 1600 here and your blitz and rapid ratings gradually declined to their current levels.
You probably should have started at 800 and then you would have won more games.
The main point of ratings is to help you find good games.
So...
Chess.com is rigged because of its rating system, some 800 and 600 play as strong as 1000's in chess.com, I am unable to understand the reason, but Li-chess is much better than chess.com. I was playing against 800s in chess and couldn't understand why I was winning 2-6 games in a row and losing to some. I decided to start over in li-chess, turns out I am far better in li-chess with a whopping rating 1500 in rapid and 1300 in blitz after playing 20+ games. Any reason why this could be??
