I have been seeing this used in people's codes and wondered what are the uses of this in Competitive Programming? I am genuinely curious.

it forces your code to throw an exception if you have an input error. so for example, if you were reading a number up to $$$10^{18}$$$ into an int, it would cause your code to get an RTE instead of WA. it helps to figure out what's wrong when you get a WA verdict vs. an RTE.
