Basically, risk management is not something that will completely prevent you from the risk of loss, or in other words, no matter how good the risk management you have designed, the risk of loss will always be something that may happen at any time without any indication, but of course one of the reasons why having the discipline to always apply risk management is because the possibility of loss that you will face will be less frequent than if you trade without having any prevention plan.
Profit is nothing more than probability and it also depends on how much knowledge you have to execute the market correctly at the right time, we must remember that our goal here is to seek profit, meaning this is the reason why focusing on various risk management plans that lead to prevention must also always be maintained and do not just focus on various ways to get the benefits.
Risk management is to minimize risk, it does not mean that when we are able to learn risk management, the risk will disappear, in trading the risk is very large so it is important for us to learn to minimize risk.
It is true as you said that everything comes back to yourself to learn everything before deciding to trade and wherever we seek profit will be comparable to the risk we face, it cannot be denied.
And regarding the many traders who experience losses, I think it is common, everyone must experience something like that, but it can be used as a lesson to be a turning point for us to learn better to be able to turn things around, namely getting profit like our initial goal in trading.
Trading is always full of risk, we cannot trade risk free in trading. We must accept the risk. But trading cannot be done without knowing anything, because when we learn about trading, it is possible to reduce the risk of trading by various strategies, which greatly reduces the amount of our losses. So we need to learn trading, and fully understand trading and then trade.
