Some scarring means that some irreversible damage has been done to the liver. Scarring in the liver and cirrhosis are synonymous, so the diagnosis doesn't mean you have a conditions where your liver is doomed. The scarred part no longer performs any function but the liver is a huge organ and it can sustain a lot of damage before it causes health problems.
Damage from hepatitis C can follow all sorts of paths. Some people get no damage. Some people have several flare ups over a life time, and minor damage is done each time, but there are problems caused by the damage, and some people have a gradual and progressive decline in liver function. There's no way to know for certain what will happen to you in the future, but at the moment, you have fully-functional liver, and it appears from the doc's comments that the damage is not progressing at this time. Maybe it will never progress again.
Even in the worst case of progressive damage, it usually takes several decades before liver function declines to the point where it starts creating health problems. If your liver was eventually destroyed a few decades from now, you might be able to get a liver transplant from a living donor. In 10 -20 years they might even have a more effective treatment or cure. All you can do in your situation is just go on with your life as you would if you didn't have hep C. Your prognosis at this point is still pretty good and the odds are still in your favor that this condition will never have much of an impact.
I have had this for 35 years and up to this point, it has never caused any symptoms.
