What does Sir Kazuo Ishiguro mean by a humbling experience in the following?　”Humbling" in this context cannot mean "something makes him feel insignificant or inferior" as some dictionaries define, can it?

Sir Kazou, 64, was today knighted　for services to literature by Prince Charles at Buckingham Palace. Speaking afterwards, the best-selling author described it as 〈a 'humbling experience'〉. He added: 'It is all part of my story of coming from a different country and growing up in this country. ' 'It is part of my big love affair with Britain and British culture.'
