One UI core and One UI.

Hi... basically, One UI core has only the core features that help to run the device day to day. But on the One UI, there are many advanced features like Game Launcher, Good Lock, Link to Windows Knox Security and many more.
Easily you can find it by settings > about phone > software information.
At the top of the menu, has either One UI version or One UI Core version. Or else, you can check from following link and select "Devices running One UI"
(But sometimes it is late to update. Better if you can search the device model number from Google before buying)✌️

One UI is often rated by reviewers and tech enthusiasts as one of the best Android skins out there given how versatile, feature-packed, and user-friendly it is. One UI Core, on the other hand, is a light version of One UI found on less expensive Samsung phones.

One UI Core has fewer features, but retains the same design language and comes with a lot of the same pre-installed Samsung apps found on One UI. Core is not as well optimized, but given the price at which it is available, there is not a lot of room for complaint.
