Yes the difference between integral spin (bosons) and half-integral spin (fermions) particles is one of the most important facts in physics. The two types of particles behave very differently, fermions obey the Pauli exclusion principle and therefore act like matter in the sense of exclusively occupying space. Bosons have no exclusion principle and behave like what we typically think of as energy, light for example. Superconductivity and superfluidity are also manifestations of bosonic behavior in collective systems.
