What is data point in Machine Learning, what means data point, data point deep learning, data point meaning, why data point name, data point statistics

How a row of features (for example Name, Age, Sex et.c) can be named simply as “data point”? This can be not that obvious.

But if you think about some set of features (x1,x2..xn) they may be represented as actual point in n-dimenstional space.

For example on a 2D plane of Work experience (x axis) and Salary (y axis) specific work experience and salary can be shown as a dot/point on a x-y axis, for example with coordinates (10, 70,000) – 70K$ for a 10 years of experience.

So a “data point” from ML/statistics vocabulary fits perfectly here.
