That didn't happen and Bird by happenstance gets paired with the strongest blader in the tower and a Beytuber that's only strong from losing to someone better than her on a daily basis. So the kid literally never had time to actually grow and get acclimated to what it means to be 'pro'. Bird's just riding coattails and he knows it. And it's not as though he's a shitty blader, even Wyvern's user, the tester, was impressed by his growth to pass the exam to move up. The issue is the manga, and subsequently anime I'm assuming, are going 0 to 100 with no buildup.
It's the Rantarou Kiyma situation again. For all the L's he took in Burst, the kid was still considered among the best in Japan and by Sparking he's ranked 15th best in the world which still speaks volumes for his talent. Only difference is we got to see Rantarou grow as a blader as opposed to Bird who was glued to two auto win buttons.
