So I just got back from a small concert and I am not sure I am doing concerts right

I have been to three live concerts in total, the first was Imagine Dragons so obviously that one was massive in a basketball stadium, the next was Wardruna so slightly less massive in a concert hall and the last was Moon Walker in a pretty small venue. So standing through a whole concert kind of sucks and the most recent one didn't even have an option for sitting. And the one that I actually could sit at had the most uncomfortable sets I have ever been in. And despite having silicon ear plugs at the last two, I could understand most of the words being sung with the drums drowning out everything at the Wardruna concert. This was once I might have thought that venue had poor sound balancing but twice in a row? The nice thing about the most recent concert is that the openers offered to chat with fan at their merch tables but since they were in the same room at the on going concert so it never really felt quite enough to talk to anyone. I don't know it feels like everyone else there got way more out of it than me that is a sucky feeling.

Edit: I'm going to bed so won't reply for a while but you answers have been reassuring and helpful.
