Is accuracy EVERYTHING?

If you have been in machine learning for quite some time then you must be developing models to attain high accuracy, as accuracy is the prime metric to compare models, but what if I tell you that model evaluation does not always consider accuracy only. When we have to evaluate a model we do consider accuracy but what we majorly focus on is how much robust our model is, how will it perform on a different dataset and how much flexibility it has to offer. Accuracy, no doubt, is an important metric to consider but it does not always give the full picture. What we mean when we say that the model is robust is that it has realized and learned about the data in a correct and desirable manner, hence the predictions made by it are close to the actual values. Due to the enormous mathematical techniques involved and uncertain nature of data, it may happen that the model results in better accuracy but fails to realize the data properly and hence performs poorly when the data is varied.
