I believe your overall statement is true, but that doesn't mean "People don't leave jobs; they leave managers." is wrong.
I have left jobs because I had a shit manager, but he was enabled by a shit company culture.
My teams were mostly great, the tasks were okay.
It might have been time to move on regardless, but the biggest reason was shitty managers and shitty company culture.
