He could hardly be expected to play his chances down, could he?
He didn't even say what the headline claims (as seems to be standard these days).
I think he's just saying that he's hopeful of being back to full fitness by then, so he has a great chance. He's not the only one with a great chance of winning, but it's much better than most.
In terms of ranking, I'm sure Andy would like to have a higher ranking, but he doesn't and worrying about the problems of having a lower ranking would only distract him from improving his game, and ultimately his ranking.
Talking of weak dodgy headlines, I do despair that "news"papers act as if something is a scandal in a headline (the hotel getting reviewed before it opened), when even their own article explains that the reviews actually came in after it had opened. Actually, the "questionable reviews" themselves explained how they were able to review it before the official opening.
