Did Scott actually learn anything?

At the beginning of the film, Cassie criticizes Scott for being complacent. She teases him that after defeating Thanos he hasn’t really done much. Well, he then goes into the Quantum Realm, defeats Kang, comes out, and… is back into the same routine. If anything, he’s less sure of himself because of the whole Kang thing. Did he learn anything? Did he grow as a person? We honestly don’t know. Maybe he learned to respect his daughter a bit more? But it’s weird that Scott saves the world and starts up a new era of the MCU, but sacrifices nothing and doesn’t use the experience as a springboard into any kind of meaningful change.
