@pendesk8, it sounds like you need to keep asking questions until the explanation makes sense. There are reasonable reasons that surgery may not be possible. Generally speaking some pancreatic cancers are inoperable or unresectable if the tumor is too large to remove or your cancer has already spread to other parts of your body. This can include locally advanced cancer. Locally advanced cancer is cancer that has spread outside the pancreas. It may have spread to the large blood vessels near the pancreas, or to a number of lymph nodes.

Sometimes, stage 3 cancer is borderline resectable cancer. This means that the cancer has grown very close to the major blood vessels near the pancreas. You may be able to have surgery to remove the cancer, but it depends which blood vessels are affected.

If your cancer isn't operable, there are treatment options, which may include chemo, radiation, immunotherapy and/or targeted therapies.

I would ask more questions and consider getting a second opinion from a major cancer center or center of excellence like Mayo Clinic.
