Idk if it's just me, but it seems impossible to pass skill checks without the result being at least a 30 or higher.

I've played numerous worlds and it feels like if I'm in any world besides a proven DND world and even in a lot of DND worlds if you don't pass a 30 on a skill check then nothing happens or almost nothing happens. Like I can't Persuade someone of almost anything new unless a 30, I cant interact with any special artifacts or get any really good knowledge about any mysterious artifacts or people unless my roll is 30 or higher. If context is heavily on my side, then there's a chance that I could get it with a result of 20. I'm not sure about other people's DND games, but in the ones I've played and with my knowledge basically if I roll a 20 or higher most of the time things should heavily go my way, if not then you need to be high to mid level, have expertise in the skill, and have a +5 to that stat and a very high roll for you to even scrape at chance to getting a 30 on a skill check. It's to the point I genuinely almost always give myself advantage and a plus 10 bonus to most checks to make it reasonable. This could be mitigated somewhat if mechanics were in place for Passive skill check levels, so you couldn't ever roll lower than a 10 or something so with your high rolls you couldn't have a result lower than what's reasonable. It might sound like I'm being unreasonable and always want to have high rolls or something, but often I'm trying to play this more as a narrative story, not a game, and in a lot of cases it doesn't make sense for the characters to not be able to do the basic things they should be able to do with their abilities. The problem with the “Need to be at 30 roll” problems solution of giving yourself stupidly high modifiers is that actually often it feels like you're constantly winning and breaking the game, but the only alternative is allowing the game to have you fail at best 90% of the time instead. So you either perpetually win, or you perpetually lose and then randomly win, but that problem is that you can't choose when you win, so you could literally be talking to someone and trying to convince someone who's lactose intolerant to like cheese, somehow win that, and then later when you're fighting the demon king you can't roll high enough even once that you just automatically keep failing.
