Yes that is correct I think some players don't know about some teams that are 90th lets say and those teams don't get as much attention.
However i can understand what BC hostivar is saying because if someone plays against a higher rank they will try harder to beat them and then the high ranked team may be forced to use enthusiasm in the future.
I agree with the country rankings but maybe only top 50, i mean some countries don't have 100 active users ; ).
