Yup. There was a famous talk with a astrophysicst (forgot who and the name of the talk) where he was demonstrating this in an ELI5 manner which made perfect sense.
He was saying in the future even with the greatest advancements of technology and telescopes if they look at the sky they won't ever see anything and there will be no clue of there were other galaxies (or clusters, not sure) ever, because of expansion and redshift.

It’s depressing. All this stuff that we will never ever be able to explore, and won’t even know exists at some point. I’m not even remotely religious, but sometimes I like to think that after death, we still continue to exist, but free from the constraints of physics, so we can explore the whole universe, through all of space and time.
It’s even worse than that. Since universe is expanding, there is limited area that is possible to reach with the speed of light. In 200 billion years other galaxies are not going to be visible anymore.
