Why does my edit code page look different from video tutorials?

My edit page looks different than every video tutorial I watch. And there are a few other differences scattered about too. Of course I’ve just started here and don’t know what I’m doing, so any input would be much appreciated. What’s going on? Why do I have this graphic (shown below) in place of the ponytailed man graphic everyone else has? It’s not just an aesthetic concern, I’m experiencing functional differences in a number of other places (some prompts are different, etc), but maybe this gosh darn graphic looks familiar to someone.

Hi,
I have the same graphics. It just Shopify updated the design and some functionalities, and now everyone will eventually have the same structure.

Thanks!
