The "learning not winning" thing is bogus. It's psychological trickery to take the pressure off big matches. Many guys have said that recently. If I'm not mistaken Yianni always used to tout that.
The reality is they compete to win. They want to win. They care about winning, and especially care about winning big matches and big tournaments. They'll all be disappointed if they lose at NCAAs or the Olympic trials/Olympics.
Claiming that you don't care about results and only care about learning is deception and denial of reality. That said, it does seem to work for many guys by taking the pressure off. I just don't think it should be taken as a genuine statement of achieved nirvana but rather a window into how they mentally compartmentalize the challenges and stress of elite competition.
