No, locally (i.e. the known universe) there is much more matter than
antimatter - why is one of the big questions in cosmology.
Every kind of particle has a corresponding antiparticle - electrons
have positrons, protons antiprotons, quarks have antiquarks etc. The
exceptions are those particles that have themselves as antiparticles,
such as photons.
