Gamma ray burst is a source of a particular type of cosmic rays.
Cosmic rays are high-energy particles arriving at Earth from sources that lie outside it. What exactly is "high energy" in this definition is not well defined. Practically any stable particle can be a cosmic ray. Thus you may have photons (gamma rays), electrons, protons, nuclei, neutrinos...
The most common type of cosmic rays detected on Earth are actually protons. It has to do with the fact, that a high energy proton can travel very large distances without losing significant energy. High energy electrons relatively easily lose energy in collisions with CMB photons (reverse Compton scattering). Highest energy gamma rays can also collide with visible photons, or even microwave background and produce electron-positron pairs. These effects reduce the distance from which those types of cosmic rays can reach us. Neutrinos could be abundant, but are difficult to detect, mostly they pass the Earth without any interaction. This leaves protons and light nuclei as the main component of cosmic rays detected on Earth.
Be warned, that sometimes the name "cosmic rays" is used for particles that are detected on the surface of the Earth. The majority of those particles are actually muons that have been produced in the Earth's atmosphere by collisions between high energy cosmic rays and nuclei of atmospheric gases, so they are not of cosmic origin, they are just secondaries
