Just relax, we don't ask you to know what a myxolidic or phrygian scale is, do we? But knowing the notes on your fretboard is a big help and it will help you get from decent to better than decent. At your age, I knew the notes of my fretboard and had some knowledge of very basic musical theory; it helped a lot to analyse things, and also in a band environment. (And also; I was of Legal drinking age, thank god I live on the old continent

). I'm not questioning you're abilities on bass, but I (and I think the others as well) think that you can improve a lot by knowing your fretboard.
