So, the failure is caused by the assumptions (model), not the algorithmic approach to fit the model. Correct?


I don't know what failure you are talking about.

Optimal extraction of the model parameters from the data should always give an effect that skews the parameters towards equality more if you have less data. Because on average the probability of 'heads' for a coin that showed H heads and T tails will be (H+1)/(T+2), if you don't have any prior bias for what the probabilities can be.

So the estimated win probabilities themselves are dependent on this. That means any modeling of the win probability (e.g. in terms of rating differences) necessarily must also depend on this.
