No, it means he values fire drakes more than you and/or can contest it better than you.
The distribution of drakes for the four of them is going to be roughly uniform because each permutation is equally likely and the portions are pretty much going to be uniform.
You would have to see how many drakes per game he gets and see if that is significantly different than you. Then you have to control for the population desire for drakes. Once you have controlled for those two things, you have to peel out the interaction term between agnostic drake aggression and specific elemental desire in order to see how much he uniquely values fire drake over you.
I personally have about 8% of Air drakes. This does not surprise me in the slightest because I don't care about air. I have roughly 33% ocean because I fucking love ocean.
