What are Gambits that everyone should know about?

I personally don't know any gambit, I just try to play the opining following the basic principles. I saved this list from a comment in Reddit time ago:

Unavoidable 2nd move gambits:

• King's Gambit against 1.e4 e5.
• Smith-Morra against the Sicilian.
• Staunton Gambit against the Dutch.
• Blackmar-Diemer Gambit against 1.d4 d5.
• Tennison Gambit against the Scandinavian.
• Grob Gambit against 1.g4 d5.

Avoidable depending on the opponents follow-up but easy to get:

• Evans Gambit in the Italian.
• Traxler against the Knight Attack (Italian).
• Albin Countergambit against the Queen's Gambit.
• Stafford in the Petrov.
