my finger are each only like max 3-6 mm longer than yours and I'm fine
never had a problem with anything really
thicker fingers are not better for guitar playing, more the opposite if anything
barring demands some finger strength and that comes by practicing
and people with longer fingers only have little advantages since most stretches they can do that others can't are hardly
that useful
actually for god's sake don't worry about what others can and concentrate on your playing, look at others when you need motivation but never let other people's skill put you down that's silly
