Handling a signal with something that says "I'm explicitly ignoring this signal" is different than not handling (or not dealing with) the signal at all.

Basically these signals like SIGINT, will terminate you if you don't have a plan to deal with it. Yes, you can override the default behavior, but I don't think that is what the OP is asking about.
