Answer 1

DELETE
FROM superbet.fork_bet
WHERE superbet.fork_key
NOT IN (
    SELECT superbet_fork_key 
    FROM fork_bet_temp
    WHERE fork_bet_temp.superbet_fork_key = fork_bet_temp.superbet_fork_key
);

Changed the WHERE clause on both, looks like you tried to do an underscore where a period was required, and you named the second WHERE incorrectly, fork_bet isn’t the table, fork_bet_temp is.

If you get an error with that, post your table layout.
