First of all, Picard is dead. That thing is a duplicate with his memories.

Secondly, what/which timeline is canon? The Borg queen is on earth now, 7 of 9 is the President, but I also remember them leaving Dr Mexican in the past. I have no idea what is going on.

Doesn't matter, because this isn't the Prime Universe, or the Mirror Universe, even the Kelvin Universe. It's the Asshole Universe, which is a spin-off from the Starfleet Battles Universe. A universe where everyone's a self-centered douchebag, even the androids, and where purple Klingons eat people, Spock has a human sister who is better than he is at everything and is loved by Sarek the most, Picard's mother didn't live to be old and instead committed suicide due to mental illness when he was a boy, Picard never fell in love in his entire life because he was too afraid of displaying emotions or making commitments because of his mother's death, the Federation became cold and xenophobic after a few rogue androids blew up a colony on Mars, everyone drops F-bombs because it's the cool thing to do, and because of time travel shenanigans the Borg are good guys and the queen is a lady from Picard's time who-- despite committing a murder or two while still human-- is a "good person" who taught the Borg to give up forced assimilation.

Oh, and Khan didn't leave Earth in the 1990s, the Eugenics Wars and World War III didn't start until the late 21st century, and Guinan (who remembers everything ) apparently never met Picard or Data in the 1800s due to  the previous time travel shenanigans seen in TNG and totally didn't recognize him or like him when he showed up in the 2020s.

And Picard is dead and replaced by a positronic android with all his memories that will age and die "naturally."
