Android Updates are not Cumulative

I have a Samsung Galaxy S9 that was originally activated on Verizon, I discontinued the carrier service I've just been using it via Wi-Fi for apps for a while.

It currently has Android v10 and is at Android security Patch level 9/1/2020. I'm trying to install the latest updates and it's starting at update 23, and seems to be installing them one at a time; rebooting and running that process to optimize the apps that takes a little while. I think there's like 10+ to install, is this expected behavior is there not some kind of cumulative update, do you really have to install them all one at a time in sequence for an out-of-date device?

Android does require a sequential series of updates, so it can be pretty tedious to go through all of them for an old phone that was never updated. In addition, you should also make sure the Google Play system updates are also done (in the Settings>Security>Updates menu). These are also sequential.
