NO. The judge SHOULD throw out the case at the first hearing or whatever, after you have spent several thousand dollars, or possibly more, preparing for that first hearing. I can sue anyone for absolutely anything in civil court. I can sue anyone in this thread for causing em distress with their posts and a judge is going to take a look at it before it is tossed.
People tend to get the terms being sued and winning confused. As you say all it takes to sue someone is the filing fee but winning is different. It should be thrown out no later than the first hearing but there is no guarantee of that and then you are in trouble.
