The details
Chapter 123 is adapted in anime episode 75. That episode also covers chapters 123–124, so it is not a one-to-one adaptation.
One Pace re-cuts the anime to follow the manga's pacing, removing filler and padding. This chapter appears in Luffy vs. Mr. 3.
Netflix's live action passes through this chapter in season 2, episode 5, which covers roughly chapters 122–128 in a single hour. That is a span rather than a chapter list on purpose — the show reorders and merges as it goes, so nobody can honestly map it panel for panel.
