You'll get a lot further when you realize hiring managers also are lost and most listings are bullshit. And I mean they probably don't even intend for it to be bullshit but that's what corporations everything results in. Apply to stuff you only mostly fit. Don't look for complete fit or ability to check every box. So many interviews and jobs wind up not being exactly as advertised. If you read it as literal, you'll ace out tons of potential jobs that might have been just fine for you.

I have also had some success through my career emphasizing (with actual stories) how I know how to learn from others and on my own. So it's okay that I don't know every little thing, and then point to my past examples of adapting to unknown or unclear situations where I had to learn on the job.

Also people are very impressed by factual stories. Numbers, or specific details, etc. that give them the impression you aren't lying. Tell about times when you actually did a thing. Not how you are able to, but give an example of a problem and how you overcame. Even from school projects, team projects, thesis work. Anything.
