Rejection from Far Sector SFFH

So after many days, Far Sector finally got in touch with me to say thanks but no thanks. I think they sent a form letter, but I'm not sure. There is this:

"While readers here appreciate what’s strong about your work, we feel the work is
not a match for our current editorial needs. That in no way is a critique of your
work’s quality, and we hope you don’t feel too let down."

So, is that something they added, or do they say that to everyone? Am I insane to obsess about it? Does it mean that 235 Hark Lane needs another, tighter rewrite before it goes back into the cold cold world?

Can someone please explain the world to me?

But we don't give up, no matter what the world says. Someone out there will like this story. We sends it out again, precious.
