How is the interpolation calculated to generate 3D -> 2D ?

I understand that rendering involves retrieval from the 2D texture map. But how is a texture map created such that the rendered image retrieves the exact textural information we want? Like how do we create the 2D wrapping paper for a 3D rendering?

Have the same question - are these texture maps typically created by coloring some 3D representation, then projecting it into 2D? If so, are texture maps ever just stored in 3D?

How much is the textural information we want to represent distorted/stretched by this 2D mapping?

I know we can use modeling softwares to get the textures correct on models that are created for us, but how would we create our own wrapping 2D images for 3D models that we create and map the coordinates correctly without it being extremely tedious?
