Guys I need help with plugins

Hi, I need help by someone experienced. I'm new to fl and after a few months trying I finally understand how to use the DAW and work with it, but there's something I don't understand and it's plugins.

I understand that plugins are essential and therefore I want to use and understand them but everytime I open one I instantly get overwhelmed by a window full of buttons and numbers, and I don't know what anything in there is for.

How did you understand how they work? And how can I understand every plugin? I know this seems like a stupid or insane question since every plugin is different but let's pick one, astrosphere for example, how do you understand how it works? Did y'all just memorize and learn every plugin's "settings" or are these buttons not even used at all? I'm so confused everyone on yt and internet acts like you're some kind of master or professional and everyone says they learnt everything by practice when it's most likely not true and if it is it's extremely overwhelming imo, if any of you could help me atleast a bit i'd appreciate
