It strongly depends on your personality. There's absolutely nothing wrong in being a "surfer" skimming surfaces of everything, in a way, your hobby might be to explore things as much as things themselves, if you're not "sucked in", maybe that's just fine? Sure, you don't know anything about woodworking compared to a carpenter, but you probably know more than most, enough to ask a carpenter the right questions, or fix some things that many people would have to pay for having fixed.. You might know enough about metalworking to have an interesting conversation with a finesmith, even if he outskills you.
Maybe, once in a while, take a deliberate deep-dive into some element of one of your hobbies, and see if you're sucked in, if nothing else, to satisfy your neeed to feel less superficial, but understand that you're not doing it to test your skills, but to test your tastes, to see if it's "more" for you than a "superficial" hobby.
Time is obviously a limiting factor for most of us, for me at least, less than .1% of the things I find interesting are ever pursued because time.
