Should I try again or is it gambling?

Guys I need you advice since there might be people with more experience, I tried to win a funding account and in my third time I passed. But after that I blown my account. I really think that I should just let it go because it could be that passing that challenge was not profitable instead it was only luck. What do you guys would do? Go into paper-trading? Please give me some sense of direction. Thanks in advance and sorry for my grammar(English is not my native language). Also I know exactly why I lost, I was too greedy and that made me take the wrong trade. Mainly my emotions were the problem.
