Am I reading this wrong or what

You're probably crazy.
Nothing wrong with that though.

with that team in T15, I am not surprised.

I mean, I've been number 1 in Grand Conquests at the start of events / for a couple of hours. Basically, it's easy to be high up when you're in a limited pool of try-hards.

In the case of Arena, it might matter that on the first day of a new season, only so many people are going to be playing a fourth match.
