It can't be blamed that most beginners don't have a good understanding of Bitcoin. This is because most of them are focused on making a quick profit and skip the process of learning how Bitcoin actually works. They often jump straight into investing, hoping to make money as quickly as possible, without understanding what Bitcoin actually is or how to keep it secure. That's why it's important for beginners to understand what Bitcoin is and the key aspects involved. Having a good grasp of this can help them gain a better understanding of Bitcoin and avoid mistakes that could cost them a lot in the long run.
This can be said of newbies not in the forum, but every newbie in the forum, they might not be interested in the things of bitcoin, but in as much as they are in the forum, they will be subconsciously be learning about bitcoin. The threads we read everyday, teach about bitcoin, so anyone who has been around here for a while will have some basic knowledge of bitcoin. Unless it's someone who blatantly refuses to learn.
What Op taught about is basic, but sometimes confusing for people who are not attentive. The wallet is just an interface that enables us to interact with the Blockchain in managing our bitcoin.
