Facts are concrete objective concepts like: dogs have four legs, the sky is blue, grass is green, chlorine gas is toxic to humans...these sorts of things can be proven through observation and testing.
Truths are more general, abstract, broad ideas like Good and Evil, Right and Wrong, Peace, Freedom, Justice and Injustice...
Or a truth can be a subjective insight into human nature. Those kinds of insights are the basis of art, theater, fiction, and mythology...Truths are things that can not be proven scientifically they must be demonstrated metaphorically...
