You have to find a good balance between quality and quantity. Having a set schedule and releasing videos often is great, but people have to see you're putting effort into what you produce, otherwise the content gets devaluated. If you have an idea in your head of how a segment would look best, but you're too lazy to google on how to implement it in the video editing software you use, just drop YouTube as a whole. You can't lazy it out on quality, not in the current landscape of the site.

Your video portfolio matters. This is why releasing videos regularly and with good quality is important. When YouTube algorithm does its magic and pushes your video to many viewers, they will be curious to see your other work and this will be the determining factor as to whether they're going to sub. If you have a solid number of good content that is released regularly, that equals value. There are exceptions of course, but most of us are outside of the realm of exceptions, otherwise we wouldn't be here.
