It depends. Sometimes a true story can be exaggerated or have some details changed for dramatic effect, but the core events are often based on real happenings.
It's a bit complicated. A true story might be mostly true, but details could be changed or interpreted differently. Plus, people's experiences and recollections can vary, affecting the accuracy.
I don't have definite information. It could be a mix of truth and creative imagination. You'd have to do more research or look for official statements to know for sure.
