Confusion about sound banks

I see Arturia is having a winter sale on sound banks. We just got a minilab 3 and it came with Analog Lab Intro. It looks like from the FAQ on arturia’s website, I can use any of these purchases soundbanks inside Analg Lab? I’m confused by something though. These sound banks list individual instruments they’re associated with. So are you essentially just buying certain sounds within a given instrument like say the Jupiter 8 or Juno, etc? With so many sound bank options, plus different software instruments I’m just really confused on what you’re actually getting.
