Just to be sure, we are out of the box we GA if you enable it ?
And universal analytics handle all of them ?

Yep I saw that 😄 but is all analytics except google are using a ga variable ?

You can implement GA into a website in two ways. In a legacy way (using _gaq.push()) or like Universal Analytics (ga object).
Magento out-of-the-box supports both:

That's why I test both and use the right code for the one enabled.

If the owner of the website uses something different or want to use it in any other way, he can define his own push function .
