Highly unlikely it has even Learned anything, since in a mile it more than likely never went over 160°F to get to that point to even start the process.

Other than a much needed oil change from being contaminated, it didn't seem to hurt a thing. If the throttle body dumped enough fuel to ruin your rings, I'd bet money the car would barely even run and would be belching black smoke out. I know mine was, and it's still running great after a WBO2 sensor replacement.
