Just to end this thread, there's a bunch of stuff that I knew IRL, but I didn't know in BG3. I still don't know why my hit% was so low, but after playing for a few hours, I now understand combat. Not being a keyboard/mouse/PC gamer didn't help me much either. I didn't know I could rotate the camera until more than an hour into the game, which made combat and exploring more difficult for me as well. Bad, old age, eyesight regarding reading tiny text on screen didn't help me either--but at least I know where to look now and that I must wear my reading glasses when playing.
It's a lot different than I play D&D IRL, where for the last 30 years, we've always focused on role over rolls. This is more like what an AI DM would be like with RAW and using every known rule, which to be honest, knowing the rules and knowing the rules are different. With tabletop/friends, the GM can help/remind and guide the encounters to make the players feel like heroes/challenge without punishing them for forgetting or thinking they did something. I know (most of) D&D rules, but that doesn't mean I remember all of them at the correct times. I have often relied heavily on the DM (or players when I was DM) for some rules, since we've always focused on story/characters and used rules as guiderails to the story.
I still feel my first character I created is cursed, since even knowing how to play now, I can load that character and then fail multiple DC 10 checks (with advantage and with boosts from cleric spells and inspiration) in a row. So I just retired that character. Maybe there's hidden feats, unlucky or cursed, assigned to that character or something.
At first, I kept thinking that if I didn't see the dice pop up then I wasn't getting disadvantage (I was waiting to see 2 die and the rolls). And I never noticed the tiny text in the top/center of screen that lists the status/disadvantage/advantage until hours later. Also, I'm pretty sure everyone had darkvision, but I feel I didn't understand the shadows/light effects for combat either. And lastly, killing Commander Zhalt was pure accident/mistake when I left Us by the restoration pod, hoping to give me some free heals during combat, but Us ended up blocking the other 2 soldiers from entering.
I still plan on playing on Story/Explorer mode, but I still wanted to understand what I was doing, even if I were getting the Easy mode bonus.
Thanks to everyone who tried to help me. I was just very confused.
