You are good, making profit while learning. Just consider later on: How much time did I „spend“ while investing. You spend something. That’s a thing you have to calculate as well.

I started investing about 3 or 4 months ago with $250. Through a few trades during these months, I managed to increase it to $380 without taking on excessive risks. My question is, am I doing a poor job? Note: I'm a beginner.
