Only nine types of element (memristor not included), five passive and four active, are required to model any electrical component or circuit

As @Huisman points out, this statement applies only to linear ideal elements. Specifically, the statement does not apply to non-linear elements or, in general, to real elements. The structure of the article suggests this distinction but the single sentence, taken out of context, can be a bit misleading.
Having made that qualification, I think the statement is correct. The only way to prove that it is not correct is to produce a counter example and I can't think of one.
"Any electrical component or circuit" is far too broad.
The elements being discussed only apply to lumped-circuit models, in which the connections between elements are assumed to be ideal — no resistance, no electromagnetic field (parasitic) effects, no delays, etc.
Such models are by definition only an approximation to real-world circuits to begin with.
