I sincerely hope you’re remark here is sarcastic. Chat GPT is not a source I would trust or rely upon, nor use for creating code.
I’m mainly learned this stuff myself, but I do have a major in computer science as background, which I reckon most people don’t have. However, lurking in the forum and learning to search for answers can be very helpful. There is also a dataview example vault which holds a lot of examples of both data structures and queries to use. Not sure how updated it is to recent changes, but it’ll still be a good resource for learning the ropes.
