I don't know much about the partner program but if I change the wording to this:
"You _could have_ earned x$ from your first video. Good job! You're on your way to the Partner Program please supply your financial information and a scan of your ID for future payment."
Since you seem to have experience. Did you notice 15 minutes of fame on your first uploaded video? How many views did your first video get? What was the topic and soundtrack of your first video? I'd love to dig a little deeper.
I agree that it's likely intended to give new users that hit though.
