This is all you see, the first 5 parts on the left are my files, photos, apps and so on. Then the wide bar called Family just shows me the space everyone else is using. If they look at it they also see their breakdown on the left and what everyone else is using on the right.
You just need to remember that if you cancel the family plan, anyone using more than the standard 5GB will lose files unless they upgrade.
You as the 'owner' of the family plan cannot see or access anyone else's files. A lot of people think that is a thing too.
Really a case of everyone still has their own iCloud account and that is allowed to grow within the new pool size.
