Please teach me how I can get YouTube to stop showing me videos about cars and food reactions. And American local news channels. Dislike button does nothing.

Please teach me how I can get YouTube to stop showing me videos about cars and food reactions. And American local news channels. Dislike button does nothing. Hide because I don’t like this video option does nothing. It hides that video and keeps recommending competing channels on the same topic. Don’t recommend channel button blocks the channel so that three more competing channels on the same topic take its place
