How hard have you tried to do so, is the question.

android has user profiles (although most oems disable them in their custom roms), you can just create multiple users with completely separate app data.

you can also create a single Work Profile for each user (which is available and works on basically all devices).

Samsung also has a built-in sandbox feature (“Secure folder”)

There are hundreds of apps that can create a virtualized sandboxes (by running apps within themselves and hooking into api calls)

And of course apps can just be cloned by just patching them to change the app id.
