Yes to all of that!
It is imperative not to take any of this estimate stuff as gospel, because even the CB itself goes back and "corrects" its old estimates as its assumptions shift over time.
Case in point: Chicago
Chicago 2020 count: 2,746,381
Chicago 2023 estimate: 2,664,452
Chicago 2024 estimate: 2,721,308
So does that mean that Chicago really grew by +56,856 (+2.1%) last year, instead of +22,164 (+0.8%)?
No, it means that the CB also adjusted the 2023 estimate up by +35,692, likely because the CB now believes that it was previously overestimating how many people actually left big urban cities during the pandemic.
Using any of these estimate figures to make definitive statements about which cities are growing or decreasing faster than others is a fools claim, as the CB itself doesn't even stand by its old figures. Who's to say that any of these new estimate figures won't be adjusted again next year?
