The outsized emphasis on dietary cholesterol, a molecule, and its relationship to blood "cholesterol", a type of solid particle (many aggregated molecules) composed of fats held together by cholesterol and proteins, is mostly a verbal confusion. Your "blood cholesterol" is the number density of lipoprotein particles in your blood. It is not the concentration of dissolved cholesterol qua cholest-5-en-3beta-ol.
