Curiosity can sometimes look like humility, but they're distinct.
Humility is recognizing you don't have all the answers, while curiosity is the drive to seek them out.
Different types of humility are also distinct:
intellectual (free floating ideas)
pragmatic (situated in real operational problems).
emotional (mindset)
You can have curiosity or humility in any of them.
If you have humility in one but not the others, you have a blindspot that could be quite dangerous.
"I'm humble and curious, so the person who is missing something must be them."
