Apple ID cash vs Apple cash vs Itues gift card

[redgreenski]

I apologize ahead of time if this is not a proper section of the forum.
Can someone explain to me what is the difference between Apple ID cash, Apple cash and iTunes gift card? Can any of these forms of currency be used to pay monthly iCloud subscription?

I know the iTunes gift cards can, not sure about the others.

Per https://support.apple.com/en-us/HT208687 you can use Apple ID cash to pay for iCloud subscription. I *think* when you use an iTunes gift card you are putting the balance of it into this mechanism,

Apple cash uses the cards (debit or credit) for funding and is often used to send money to / from people you know.

I guess you could look at it like Apple ID cash is store credit to spend on Apple stuff (music, icloud services, apps) and Apple Cash as virtual cash wallet to send money to people.
