Yes, they are....80% of all stars is a red dwarf. When you hear some say that the Sun is an average star, that is a bit of a furphy. In actual fact, the Sun is in the top 4-4.5% of all stars for every physical characteristic pertaining to stars. Most of the bright stars you see in the sky make up less than 0.1% of all stars. Stars like Procyon (F Class stars) make up about 1% and the K class stars make up around 10-15%, G class stars make up about 5-10%.
So, if you take our galaxy and the minimum number of stars believed to populate it (400 billion), that means 320 billion stars are M class stars, 60 billion K class stars, 16 Billion are G class, 3 Billion are F class, about 1 billion are A class and the rest are O and B.
