Dropping you into the deep end and expecting you to find your own way is kind of a hallmark of the series. Almost every game starts with a basic overview of the controls and then a difficult boss you are expected to lose to. Even the controls overview is entirely skipable because they are in the form of messages on the ground. In a way this teaches you about how you interact with the world because the storytelling is almost entirely environmental. Going against this would upset a massive fanbase because this is a very well established series at this point.

At a certain point in the story, you can respec all your stats. If you mess up or want to change anything - this happens after the second major story boss. The only thing that you truly need to know about to be successful is weapon scaling. All weapons scale based on a specific stat, ranging from E-S with E being the weakest scaling and A/S being strong scaling. The number on the left when you're in your equip menu is the base weapon damage based on its level (normal weapons can be level 1-25 and special weapons 1-10. You unlock the ability to upgrade weapons pretty early in the story) and the number on the right is the additional damage you'll have added based on a combination of the weapon's scaling and your own stats. You can be quite successful just by understanding these two mechanics because they will make up a good portion of your damage.
