In the spirit of learning no tutorials should come with textures or models.

The purpose of the tutorial is to be able to watch it, replicate it, and then using what you learned create you own. Tutorials are just teaching the workflow and how to avoid some of the common mistakes they aren't supposed to just spoon feed you everything or you will never learn and never be able to complete your own work.

Work on making your own textures like Jay said even if they provided the texture file it wouldn't fit your model the same way.
