That's a race essentialist myth[^1]. There are no "white experiences" or "black experiences". We assign "white" and "black" labels to diverse individuals with diverse experiences who process their experiences differently. The average black person may have a different experience than the average white person, but the variance is so large (more variance within a race than between races) that this is utterly useless for talking about any individual (the "average white person" and "average black person" don't actually exist).

[^1]: I would say "a racist myth" but that's a bit overloaded these days and it carries some judgmental connotations that I don't want to imply, but it is no less racist than other racist myths.
