Although what you describe might be true for many of them, to suggest it's true for all of them is incorrect... I learned pretty much everything I know about current KODI configurations from a multitude of other sites and Youtube videos not just this site... There are plenty of Youtube videos that are not about installing a build, but instead are about tweaking a skin or what not to your liking, and there are plenty of Facebook groups that well beyond installing a build as well... I do like this forum and the add-ons the sites developers make as they are some of my go to add-ons, but it's far from the end all of information and/or add-ons in the KODI universe...They are not experts, far from it, they claim to specialise in Kodi but that is simply not true in most instances. It's all about revenue, making pointless videos navigating around some build and opening a few addons does not make you an expert, they are just after subscribers to make them money. If you want help then ask here, if you read the youtube comments of these people you will see they haven't a clue how the whole system actually works, they simply promote one-click solutions (builds) in order to generate revenue.
