For example, if I’m casting a spell on a victim in 5e, I know what the DC is.
For something like “finding the trap”, in D&D that’s pretty open to the GM. I usually tell players the target number before they roll, so they can better decide if they want to use more resources or rethink.
Depends on the system, style, and context.

Other systems might have more specific rules.
