Do you think Garp went and beat up an apprentice?
Lul.
Obviosly he fought against the "adults" there.
And Garp ofc is not in that panel, he has nothing to do with Kaido for what we know. His rival was Roger, and his era practically ended with his death. After that he was still destroying some pirates, but none notable (aside from Shiki ofc).
Sengoku and WB didn't see each other in decades, so with Garp can be the same case.
This panel doesn't put Garp below since Roger himself put Garp and Sengoku at high lvl. And that's the word of the Pirate King.
