Doubting skills as a biologist using ML

I feel like an impostor using tools that I do not fully understand. I’m not trying to develop models, I’m just interested in applying them to solve problems and this makes me feel weak.

I have tried to understand the frameworks I use deeper but I just lack the foundation and the time as I am alien to this field.

I love coding. Applying these models to answer actual real-world questions is such a treat. But I feel like I am not worthy to wield this powerful sword.

Anyone going through the same situation? Any advice?
