Unfortunately, there's indeed bloatware apps that can't be deleted. Many devices come from any manufacturer with apps already preinstalled (whether it be Samsung, Apple, etc.)- some you might be able to uninstall while others can only be disabled. When it comes to apps like that, only its app updates can be uninstalled & it'll rollback the app to its factory default state, which you can then proceed to uninstall. You can also clear its cache & its overall data. Without extra software (and possibly extra risks, depending on which method(s) are tried & skillsets, certain apps are just stuck on your device
