Precisoin is how consistent you are to hitting a target, for instance if you were shooting free throws, and you always hit the front of the rim that would be precise but NOT accurate. And accuracy is both precision and accuracy. So instead of being precise by hitting the front of the rim, you would make the shot by being accurate.

The measure of how close measurements are to each other is called precision. Precision reflects the level of agreement between repeated measurements of the same quantity, indicating the reproducibility of results. High precision means that measurements are very close to each other, while low precision indicates greater variability between measurements.

Precision instruments provide accurate measurements with low margins of error, while non-precision instruments offer less accurate results with higher margins of error. Precision instruments are designed for tasks that require high accuracy, such as scientific research and engineering, while non-precision instruments are suitable for rough estimations or general use where high accuracy is not critical.
Because the built in operator has the precision and compiler knows all the precision between the operators, and it works on that precision. User can also create its own operator but the compiler does not come to know thow to make precision of this operator. Therefore we dont use user defined operator
