Buddha said that fate can really change?

The so-called "fate is determined by nature and luck is man-made" is a manifestation of Buddhist truth, but it was not invented by Buddha, but an objective law discovered by Buddha. The so-called "fate" is the blessing or karma of previous lives. For example, being born a sheep is the "life" of eating grass. The physiological structure determines that you can't eat meat and bite people, so you should avoid the pursuit of Grey Wolf. However, if you really realize your situation and know how to make full use of your strengths to survive, then you will definitely be able to fight Big Wolf in the end. At this time, you are not a sheep, but a "happy". This is the sheep's "luck" changed. -So fate can change. Buddha and many other philosophers have discovered this law.
