What are the chances that I will inherit fuchs' dystrophy if my grandma had it?

Fuchs. Fuchs dystrophy does run in families and typically develops later in life. If you are concerned, the best next step is a detailed eye examination with an eye care provider who can use a slit lamp to look for any signs of early Fuchs Dystrophy. Fuchs is not 100% transferred so your chances are likely low, but they are not 0%.
