Yes. There are exceptions... the Azure Dragon Lord is at the very least level 70, because he is an Ancient Dragon Lord and a druid of the 5th Tier Divine Magic. You progress of 1 tier each 7 levels. It is impossible for that one to be anything weaker.

As for the estimation of 80-85, it is most likely based on the Evil Tree's estimated level. But I disagree, because I think the idea that the Dragon Lords could win against that tree is based on tactics : they can fly around while bombing the tree with their frost or fiery breaths. So, even if they are merely level 55 or so on average (with the exception of PDL being most likely stronger than ADL), they could still be reasonably victorious against that damned tree.
