I agree with just about everyone’s opinion above
I do think that if you want to learn bluegrass banjo it is critical to keep using picks until you get used to them. I had a similar experience as ChrisWms mentioned. I didn’t have finger picks when I first played with a banjo years ago and it was hard to convince myself to use them once I got them. This time, I started with picks and the transition wasn’t bad. Just don’t give yourself the option of playing without. Once you are comfortable with picks, I think there’s nothing wrong with using them or omitting them as you prefer.
