Do Samsung phones come updated?

I just received a note 9 unlocked from Amazon and it did not
even have one ui out of the box, on top of that it would not simply
let me install the latest update but I had to install every update
one after another from as far back as 2018. I was wondering if this
is normal for these phones or If I just received a bad phone.
