Not sure if you read any of my post, but check out the page I posted on "Spoiler: Chapter 962", it specifically says that the Rocks remnants started recruiting 33 years ago. Big Mom was already a pirate alongside Streusen even before joining Rocks (and even had a lot of her children already), but the Big Mom Pirates apparently were formed only 33 years ago.
The first mate isn't necessarily the first to join, it's actually the crewmember with more authority after the captain. And in One Piece we usually have 2nd strongest crewmember as the first mate.

First mate just means you’re the first to join and that’s what the thread is about
Being the first to join doesn’t automatically mean they have more say or strength than other members. A first mate can be the strongest but that isn’t always the case
