The fundamental machine-learning question

Given examples of inputs and the outcomes they produced,

can we find a function that predicts the outcome for new inputs?

That function is the model. Everything else is detail.

Symbol: f(x) ≈ y

Applied frame

Ask what population the sample represents, what uncertainty remains, and how the estimate could drift.
