Lee Sedol's quote, "I don't have the confidence to lose"

He was just joking around with a close reporter.
On the day he won the first game of a best-of-three match,
a close reporter jokingly
asked, "Is it going to end tomorrow?"
So Lee Sedol jokingly
replied, "It looks like it'll be tough, I don't have the confidence,"
which startled the reporter,
who panicked and asked,
"Why? Are you feeling unwell?"
Then Lee Sedol jokingly
said, "I don't have the confidence to lose."
Seriously...
How does news get conveyed like this..
I thought it was that characteristic arrogance of the Emperor,
but to think he was just joking around with a reporter..
No matter what words you hear, you really need to grasp the context and understand the situation properly.
