Difference between a parametrized surface and manifold
$begingroup$
What is the difference between a parametrized surface and manifold?
Is it true that if $M subset mathbb R^n$ is an $n$-dimensional parametrized surface it is also a (parametrized?) manifold? I am stuck with understanding the concept of a manifold. In which cases would a parametrized surface not be parametrized manifold or vice versa?

Roughly speaking, manifolds are kind of like the union of several parametrized surfaces with certain restrictions when the surfaces overlap.

So if I have a family of $(S_i)_i$ of parametrized surfaces, then the manifold is $bigcup_i S_i $, but overlaps "count only once"?

As a set, yes. But generally we require the parametrizations be consistent on the overlapped part, so maybe not all family could become manifolds by union.
