So what fundamentally makes fermions and bosons different?

I think your question here exhibits a deeper issue than simply the Fermi-Dirac statistics.

The world that you see around you arises out of the collective behavior of a gazillion particles. You never deal with just one, or a few particles or interactions. Now, it is impossible to know the dynamics of every single one of these particles. So instead, we find a description of their

You also do not need to delve into quantum physics to talk about statistics of particles. The basic thermodynamics laws are based on the classical description of particles via the Maxwell-Boltzmann statistics. So even before QM, we are already well-aware of statistical mechanics.

https://en.wikipedia.org/wiki/Spin%E2%80%93statistics_theorem said:Bosons are particles whose wavefunction is symmetric under such an exchange or permutation, so if we swap the particles the wavefunction does not change. Fermions are particles whose wavefunction is antisymmetric, so under such a swap the wavefunction gets a minus sign, meaning that the amplitude for two identical fermions to occupy the same state must be zero. This is the Pauli exclusion principle: two identical fermions cannot occupy the same state. This rule does not hold for bosons.

From that "simple" difference, the statistics arise.
