The sentence could very well be correct, actually. Qubits, the basic unit of "information" in quantum computing, are quaternary in nature. As opposed to "traditional" digital bits, which are binary.

Qubits are not quaternions (or indeed "quaternary"). There exists an interpretation of quantum information theory using a quaternion formalism that eventually leads to something called density operator theory, but this is obscure even for the field.

So a Qubit can be indeed, 0, or 1, or 0 and 1 simultaneously, or numerical coefficients representing the probability of each state.

No. A qubit is a linear superposition of basis vectors in some two-dimensional complex vector space. Numerical factors representing probabilities occur only when one performs an operation on qubits (specifically the inner product on the vector space).
