Correct. When true life doesn't make for a good story, they make things up. And the audience considers it "true history."
I don't care for "Cliff's Notes" portayals of someone's life. Why don't they focus on the story of one period in his life? Two marriages and ups and downs of his career are many episodes in his life.
If a bio-pic is really successful, they blow the shot at doing a "sequel" by cramming everything in one film.
And I don't need to see them start out when the lead is "five" either. That goes the same for when I read an autobiography.
