a plane is any plane surface it usually have 3 or 4 points

You need only three points provided they are not collinear. And most planes have infinitely many points although there are geometries with only a finite number of points.

A plane can be determined by three points, as long as the three points do not lie along a single line.

Two distinct (different) points are needed to determine a line.
a line has to have at least 2 points.a plane has to have at least 3 points.______________It takes two points to define a unique line in Euclidean space. But every line and every line segment contains infinitely many points. The same is true for planes in Euclidean space. You need at least 3 points to define a unique plane, but every plane containes infinitely many points and infinitely many lines or line segments.
There are infinitely many points in a plane.
