Even taking into account galaxies, the items we observe visually aren't very far away in the scheme of things. Most galaxies you can visually observe are less than 500 million LYs. Clusters like Virgo are less than 100 million LYs. That's not very far away at all, which means that what we are visually observing can hardly be considered representative.
Yes, even the "extremely" distant galaxy clusters that lie 1-3 billion light years away and are visible in 18+ scopes are, cosmologically speaking, in our backyard.
