It is very sound logic and it's certainly true. Humility brings potential forward.
However, on the flip side, when one just...oh, for example's sake...(cough cough, totally did NOT just get out of a game exactly like this, cough cough) gets wrecked by a duo premade and a trio premade when their own team is all solo players in Bronze V, it's difficult to not be blinded by bias as these sorts of things just get added onto the ever-mounting stacked list as to things that irritate certain players.
It's simply a case of 'yeah, well, we can add yet one more thing to be mad about' and being calm about it and realizing the rarity of certain situations popping up means that, with enough DIFFERENT 'rare situations', they translate into less of a 'outlier' issue and more into a 'WHICH outlier will it be?' sort of predicament.
