If I call a snippet (inner) from a chunk that is called by another snippet (outer), how will caching the inner work?

Question

I am displaying product cards via pdoResources. Each card calls a snippet that returns certain information.
Do I need to call this internal snippet uncached (with an exclamation mark) or can it be cached?

As far as I know, caching works for the resource, not for the card. Therefore, it is necessary to call uncached - so that the information of each card is displayed correctly. I'm right?

Or maybe it does not affect anything at all, the main thing is the external snippet? In this case pdoResources. If so, should I call pdoResources cached or not in order to correctly display the information of each card?
