I often see on clothes, bags, sheets, etc. a few % of polyester in the cotton cloth label. What does this mean and why do they do it? Are they weaving one out of every few strands out of polyester? Or is the fiber itself made of a few % polyester in composition? And what does it do for the cloth?

Polyester is a very warm fabric. If you’re looking for cool fabrics stay away from polyester.
