Does traveling really expand our world?

Recently, I came across to this news saying that Korean women are among the most well-traveled women in the world. And honestly, I'm not surprised!

And as Korean, I could definitely can see why this was happening (although personally I can't fully believe this news). I think it's because there's a social / peer pressure that domestic tour is waste of time and money compare to what you can "learn" and "earn" from traveling abroad. And apparently, they say it's "waste of youth" if you're not traveling Europe?
But I just wanted to ask again, like does traveling actually expand our world, or do we just move our bodies while our minds stay the same? And emphasizing that physical travel is not the only way to explore the world. What's really important, is not the distance, it's the depht of how present you are within yourself. Are you 100% standing firmly on the ground with your own feet? Are you fully communicating with yourself? Do you KNOW who you are before rushing to explore the world, maybe somewhere that has absolutely nothing to do with your life and your future?
