Green Day is pop-punk, Sex Pistols/The Clash/The Damned etc, are punk rock, (early) Bad Religion/Agnostic Front/Adolescents/Black Flag/etc are hardcore punk. It's not just "punk" and "not punk", there are different sub-genres. What makes a song a punk song is its quick pace, progressions, and general theme of rebellion/disillusion/anti-social tendencies/etc.
This song is about being young, restless, and stressed out.
One thing that makes it so good is that it takes its chord progression from Johann Pachelbel's "Canon".
