Are they saying that any time you look you will be able to observe the same moment?

No, they mean that they can see gravity waves passing by earth now whether the gravity waves started out last week just past Pluto, or 14 billion years ago when some star first came to life. It might be important to note that the Big Bang occurred everywhere, even right here where earth sits today. Old events would be visible now if they were also just far enough away that their light or gravity wave is just arriving.

I understand it so far, but if we see light from the first momets of the universe right now, then what do we see ten minutes from now?

The part I just dont get is that if we look far enough we see the same moment no matter when we look
