Have you earned money using Technical Analysis?

I've seen some videos that teach technical analysis, there are obviously thousands of courses and books out there about this. Basically many patters are drawn on the charts, it feels like people make up lines and triangles to predict where the price will bounce and how the market will behave. From a sensible perspective, that does not make sense at all, does it?

People always say that no one can time the market. However, there are many people still believing that with a couple of lines and patterns you can make tons of money as a side hustle. In conclusion, this feels like astrology; very unrelated events used to predict a future no one else can.

So my question is: Why do so many people try to use it? Has anyone earned money through this method?
