How do i plug in my scarlett focusrite and headphones to recird vocals in pro tools on my macbook pro? I dont see space for usb to connect

you can get two USB-C to "old" USB-A for about US$10 from amazon, or many other outlets. These will work fine for modest speeds. Displays or Drives may require ones that meet a higher standard. Be sure you get the right-way round!

How do I connect my Scarlett focusrite and recording headphones to macbook pro? There do not seem to be any USB ports

All MacBook Pros have usb ports newer models have usb-c. Maybe your headphones have a usb-a connector and you need a usb-a to usb-c adapter.
