If your institution is in the list, it means they offer programs that will allow you to get a PGWP.
In order to become eligible under the Canadian Experience Class, you will have to work full-time in Canada for at least 52 weeks after you have graduated (which you can do using the PGWP).
Note eligibility does not mean you will get selected under the Express Entry system. You will also need enough points to be one of the top-ranking candidates at that time. This will depend on other factors such as your English abilities, past work experience etc.
