That’s true, but that’s one moment in the story. The post timeskip kinda solidified which trio oda was focusing on and who the most prominent characters are.
1. The post timeskip began with Luffy Zoro and Sanji reunifying while Nami was paired with Usopp and Chopper
2. The two arcs about the emperors featured Zoro and Sanji as the most prominent straw hats
3. When the straw hats were separated and the remaining straw hats needed a leader oda made Sanji the acting captain over nami
You can argue that Nami was more prominent pre timeskip, but that was 15 years ago and since then oda has focused much more heavily on the monster trio as the primary characters
