Buy at a low price and sell at a high price ) just like in life.

Hello everyone, honestly, I can't figure out how to start trading. No matter how many tutorial videos I watched on YouTube, it's just a lot of fluff and 0 useful information. I have 100$ in my pocket and a strong desire to try something, who can I watch that explains everything simply? Are there any good channels on Telegram? I'm tired of some rich snobs or info scammers who are just trying to pull another penny from my pocket.
