Trading is, indeed, a constant learning process, which means that a person who is into trading will have to keep learning and adapting if they want to stay profitable and relevant in the market, whereas a graduate is basically someone who completes their education or a specific level of education. In trading, especially when someone is doing it in a market as diverse as the cryptocurrency market, a person will need to keep updating their knowledge and information, because if you don't stay updated, you will miss important opportunities, and no trader would want that.
Some traders usually make the mistake of thinking that they have learned everything after they reach a certain point with good enough knowledge. One could say that you become very knowledgeable after you spend a reasonable amount of time in the market making trades and observing everything, but that doesn't mean your learning process is over. Even those who are extremely experienced tend to learn lessons from the market from time to time.
So, I totally agree that it's just a constant learning process that basically never ends.
Not only do people stop learning after a while, but some people also do not even START learning. They just get into trading and hope that they will make a profit, and that's it. They do not know what indicators are, what Bollinger Bands are, what EMA is, what chart reading looks like, or what head and shoulders is; to them, head and shoulders is just shampoo, nothing more. And they think they could make money from it.
I give it to you that just because you know technical analysis doesn't mean that you are guaranteed to make a profit, but at least you have a higher chance of profit than not knowing how to do it. And you are right that it is a non-stop situation; you can't just learn once and then it is done, it is not like school, where you study, and when you graduate you are done. It is never-ending; you could be 70 years old and still end up studying the newest things and one more thing and one more thing; you can keep adding more to your skill set and learn more about how to trade.
