is traveling the world really a big deal

that's not why it's a big deal. It's a big deal because you get to see how people live in different places and how they solve life's problems in their own way. You get exposed to different attitudes you're not used to but start to understand. You find cool things you would never have heard about otherwise. You smell things you've never smelled before, good and bad. That's something you can't capture in a picture.

I have zero interest in traveling.

Traveling is one of life's most exciting experiences.

and you also need the interest to do so!
