I too find it wild when people do it at a beginner stage.

Back when I was learning English during my school years, I only started seriously watching native content after I already had either a B1 or B2 certificate. At that point I already knew most of what was being said, I just wasn’t used to hearing/parsing it in real-time and without the “padding” that comes with learner-oriented content. So the gap I had to bridge there was small.

The burden of learning basically everything at the same time - word meanings, grammar patterns, native-level speech patterns and speed - sounds daunting to me. But I think if you are at a life stage where you can put tons of time into it, it works.
