I think that's a valve seal where you see the extraneous 'shim' Retainer probably broke at some point and rather than replace/change, they attempted a bandaid. Of course, begs; what happened to the pieces? Could be a clue. Without history, at a loss.
without disassembly, no history, etc. you might try a dose of "valve ease" or similar and let it run some miles and see if it quiets any or not. It'll go out with the next oil change - no risk. If still there after add, then it probably need a bit of surgery to cure what ails it.
Depending on the mileage and condition, it can be anything. You're only seeing the obvious, odd man out, out of normal thing - related or not. You might be able to better isolate which one is tapping, with a stethoscope. Can't tell from the videos. Sound seems to come from some other spot. But can't rely on a sound recording like that. There are sonic probes for that but not common DIY.
Might be one of those don't worry about it till it gets worse items. Got a 1:3 chance, it'll go away.
It could be a costly chore to cure a small noise on something one may not drive much. Plus no guarantee something else won't crop up during surgery. The "oh, while I'm in here I might as well..." cost accelerator. There comes a point where it's a rebuild bite the bullet. You may not like the results in the pocket book.
This has probably been covered before, so search the site for more info.
