They use it in the modern sense ,language changes especially modern english,it depends on your experience, tragedy to me is 99% of livings beings dying ,not so much if :a video game is out of production or if someone's child can't impinge on my sanity.Is it just me or do you also find the term Tragedy to be a bit confusing. Wiki says it has to do with Greek drama and is the opposite of comedy. Do people who use this term even know anything about Greek drama? Perhaps I am very bad at terminology from Greek drama and should know more about this? Or do people use words they don't even understand themselves?
