Looking for Simple and Honest Resources to Understand Machine Learning and LLMs

I'm trying to find some straightforward resources for understanding how machine learning (ML) and large language models (LLMs) work, without the over-the-top hype or gloomy predictions about AI. There are folks around me who enthusiastically talk about AI but don't really grasp how it operates because they've never used it. They often treat tools like ChatGPT as if they're flawless, which isn't the case. I'm searching for a short video or a website that clearly explains the basics of LLMs and ML without the corporate jargon or sarcastic critiques. It's hard to sift through the multitude of AI explainers online, and I want something trustworthy that covers both the strengths and weaknesses of these technologies. I did like a certain video I found, but it felt a bit outdated at times.
