I'm not sure why you're so confident in that 0.0% assertion. iMessage is integrated with the default/ubiquitous messaging app on iPhones, and I think it's reasonable to assume that teenagers are messaging mainly other teenagers who are likely to have iPhones (and thus using iMessage).
What do you think is beating out iMessage here apart from SMS? Snapchat, WhatsApp, various social net DMs? The biggest non-iMessage usage numbers I can imagine still don't exceed what I'd expect from iMessage, just based on its ubiquity in that demographic.
