Again, I sympathize but you come off as slightly arrogant and over confident. Those are not traits that are going to get you anywhere.
What about taking a gap year? If your parents will support it, why not apply for a working student position anywhere you can and spend a year before college doing that. If you use the search function and look for working student you can probably turn up some places to apply.
But the idea is to have a back-up plan if riding doesn't work out. You could loose interest or change your mind (I know, I know, "that will never happen!") or you could get hurt. Deciding to have a job outside of the industry doesn't mean you quit riding, it just means you finance it from a different source.
