Let's take a screen as an example.
The screen manufacturer, or the result of a screen calibration, is associated with the equipment concerned: in this case a screen.
(If we had several screens of different types, there would be another profile specific to this one).
This profile is saved IN the PC; so that all the images that arrive on that PC, are displayed correctly on the screen.
second example :
I want to print an image... the PC (it software) will use another profile, this one, specific to printers (subtractive synthesis).
As you can see, a profile cannot normally be integrated into an image...
By the way, find these profiles in your PC; they are stored there.
The image profile and the display/print profile are composed to create an output that matches the intended color of the image on the target output device.
If everybody used the same image profile there would be no image profile since it could be baked in the image apps (and this is more or less what happens for sRGB). However the designers of image formats have kept the possibility to use a different image profile, and it's all the better. For instance I can ask my camera to encode Jpegs with the AdobeRGB color profile, that allows a greater color range/gamut in the image (but requires very good displays and printers to be useful).
