Permission groups are set by the administrator to allow or disallow certain actions. For example, if you wanted to give a member only some abilities of a moderator, but not allow them to be a full moderator you would do it with a permission group.
Public user groups are groups that members can join themselves, and don't necessarily have set permissions on them. For example, a role playing site might have different classes that members could join. Members is those groups won't be any different from members in other groups, or members in no groups.
