Lack of capital or knowledge, which one is holding traders back from profits?

This question came to my FYP on X and I could relate because at a time in my life it was the lack of knowledge of not knowing how to trade that was holding me back from making profit until I started learning how to trade from my mentor and I can make some profits when I get my reading of the market right. I also had the challenge of getting capital that I can use for trading because I was depending on my trading profits until I got to know that trading needs a trader to have other jobs because you can not only depend on trading profits when you do not know how to trade excellently. Other traders are having difficulties in trading because they do not have the right information that they need to become good traders or because they lack the capitals.

What can you say about this two problems, how will you advice a trader that is suffering from any of this problems or how did you get out of the problem if you had suffered from having lack of capital or lack of knowledge. Which of this problem is more common among traders?.
