These lab values are generally obtained in the setting of an anemia where your hemoglobin/hematocrit (Hgb/Hct) are low. These labs results may be consistent with an iron deficiency anemia which would have a low Hgb/Hct associated with a low MCV (red blood cell size), and a high RDW (which means the red blood cell average diameter, referring to a chronic process in which some cells that are iron deficient are small and some are large when iron was present). In terms of TIBC which is the total iron binding capacity, this is classically high in iron deficiency anemia and iron saturation is low, meaning that there is not enough iron present to saturate the red blood cells.
