Is it normal for there to be a bunch of really bizarre .plist files under the /Library/Apple/Library/Bundles directory?

Thank you, although I hope you can understand why I would feel reasonably sketched out by the fact that 400+ files I didn't download and can't find any reference to online with names such as "kr.co.smartstudy.babysharkrun.plist" exist within my library. The issue isn't that there's system files I've never seen before, that would be silly. The issue is that they look like such obvious adware and there is no reference online that would say otherwise. So let me elaborate;

I feel like seeing hundreds of files named after a combination of terrible quality mobile games, untrusted developers and absolute gibberish suddenly appear on your Mac and reacting with "Well I don't know what ordinary system files are, 'Baby Shark Run.plist' is more likely a normal official thing Apple decided everyone needed on their system than adware!" would be insane. I searched across the internet to find evidence of them being supposed to exist for hours and found nothing before I decided to ask, literally only one website even mentions the "InputAlternatives.bundle" file.

The most information I could therefore figure out is that that specific filepath has something to do with Marzipan/Project Catalyst, which lessens the cause for concern but still doesn't tell me all I need to know to be certain that they're not malicious. I know, for example, that Twitter is/has a Catalyst app– so it can't just be "inbuilt .plists for all the possible catalyst apps," which is the only non-malicious reason I could think of them being there, because Catalysts like Twitter are nowhere to be seen, big name apps in general are nowhere to be seen and I cannot reasonably fathom why it would be this way if those files were meant to be there and aren't the result of some underlying issue.

I know .plist files aren't inherently harmful, but "hundreds of .plist files for bizarre apps you didn't install suddenly showing up in your library" is kinda the definition of adware on Mac, these files inarguably look untrustworthy, and it's very rational to be concerned about a phenomenon you cannot find information on and want to get a concrete answer before deciding what to do about them.

Seeing as there is absolutely no easily accessible information online about this dilemma, I just wanted to open up a discussion as to whether anyone is familiar with these specific files (etc. "com.abc.carparking.game3d.plist" "com.banditmovie.slotsofvegas.plist") and can confirm that they're not out of the ordinary– because they very clearly look like spam, and there is nowhere online that mentions that they even exist. If they are ordinary files for a person who's never downloaded any of those apps to have, then it's good for there to be a question online that confirms that. If this is a sign of malware, then it's good to make that known as well.

Thank you.

Thank you. That's all I needed to make sure of.
