FALSE!

There are an infinite number of planes containing any given line; the 3 points could be on the same line.

Any three NON-COLLINEAR points lie on exactly one plane.

Three points always lie in exactly one plane.
------------
3 points define a plane if they are not co-linear --> true.
3 non co-linear points define 2 lines which intersect and form a triangle, which defines a plane.
---------
If they are co-linear --> only 1 line --> it's false.
