I understand the necessity of comprehensible input, however how do you get to that point in your language learning?

Hi there, so one thing I’ve always had trouble with, or not necessarily understood how to do, is get to the point where things become largely comprehensible, it’s always been a couple sentences here and there. I’ve seen decent progress in my Italian by just watching a lot of YouTube, Netflix, and passively listening to things whenever I’m enjoying another hobby, is it just a grind to get to that level where you can find comprehensible input? Whether that be kids tv shows, or native level programmes for adults. Any help would be greatly appreciated.
