The ability of your heart and lungs to deliver oxygenated blood to your peripheral tissues is a function of your cardiovascular, peripheral vascular, and pulmonary health.
Muscular endurance is more a function of your skeletal muscle to exert force against resistance over a given period of time. Your muscular endurance is determined by multiple factors. The muscle bulk itself, in addition to how strong but flexible your tendons are, how well (and how many) motor neurons communicate with the muscle tissue, and how many functional units of a given muscle are able to be recruited for a particular motor response all play a role in muscular endurance.
For someone to have muscular endurance they need to be able to perfuse their muscle tissue, so your statement is partially correct, but having a more complete understanding of what goes into a muscle's ability to exert force over time is needed to make a full statement on muscular endurance.
