Stuck with a poem: What do SEE and NO WONDER mean in here?

this is from a poem:

“Oblivious to look and word/They pass, and see no wonder”

What do “see” and “no wonder” mean in here?

“See” means notice, and “wonder” here means a marvel or something amazing. I think the line means that people walk by and don’t notice anything to amaze at or admire, even though it’s probably there.

No wonder. I thought “no wonder” actually meant “no wonder”.
