Understanding Levels on Pro Sites

Ok, just so I make sure I understand the levels, in pro sites.. correct me if I am wrong.

Ok.. each level represents a certain membership access, correct.

But users can have like 2, 5, 8 Levels.. and only have access to what those levels have access to, correct?

In otherwords, if a usera has 2, & 5 they don’t need to upgrade levels progressively, say 1, 2,3, 4 in that order, right? They can be on level 3, 8, 10 all independently of other levels, right? I hope so. Thanks again.
