In Asia they're ubiquitous and that's already like 60% of the world. I looked up South America and Africa and they're apparently also the norm there. I'm not sure where they aren't the norm besides the Anglosphere and Europe, so maybe ~15% of the world.
I don't think this is anywhere close to accurate, because on the continents you count as full-service there are definitely individual countries that primarily have self-service stations.
My experience driving in Japan for three years is they weren't the majority there. Mostly self pump
Looking it up for Japan in particular, it seems that they're (self service) starting to become more common in rural and highway areas, but full services remains the comfortable majority.
