You can definitely learn trading for free, if you really want, there is Meany way. There are many free trading classes, courses, and videos available in various places that are very essential in trading. It would be better if you find a professional trader offline, to whom you can learn about trading directly. But it will also take you a lot of time, because trading is such a thing where all the money is lost due to a little mistake, it will take about 2-3 years to learn trading completely. If you use money in trading without learning trading completely, you will only lose them. So be it for money or free, after learning trading thoroughly you should start trading with money.
I personally don't believe that there's meaningful gaps between the experienced and the newbie, I mean yes the experienced are more mentally resilient and knows the how the market works but newbie too can figure out such thing in short amount of time if they are attentive enough, the important thing to learn in my opinion is something like the basics, the principle of economy, trading, the platform itself since we gonna do activities mostly in these exchange platform so knowing the features is good thing.
by then if someone just want to try out they can already know some basic knowledge and could built their experience from then, helps from expert trader at that point is no more necessary.
even though its always good to have mentor to point out a mistake or two, but eventually we gonna figure out everything by ourselves not too much dependant on someone.
