I tend to think of "warning" as - "something unexpected happened, but it was handled safely"

And then "error" as - "things are not okay, a developer is going to need to intervene"

And errors then split roughly between "must be fixed sometime", and "must be fixed now/ASAP"

It was handled safely at the level where it occurred, but because it was unusual/unexpected, the underlying cause may cause issues later on or higher up.

If one were sure it would 100% not indicate any issue, one wouldn’t need to warn about it.

That would indicate an issue - i.e. something we don't want. Just that it's not something where an engineer needs to go and mop up, and in theory would continue to operate correctly indefinitely. I guess correct as in - safe but not necessarily the most desirable behavior
