Is apple one family iCloud storage shared?

I currently pay for my own 200gb iCloud storage. If my family buys the apple one family plan, which includes 200gb of iCloud, does that mean that the whole family shares the 200gb? (At about 40gb each, since there are 5 of us) OR do we each get our own 200gb of storage?

If we pay for the premium plan, does that mean that each of us gets 2Tb? Or does that mean we each share the 2Tb, for about 400gb each?
