Yes, oxygen is lower in higher altitudes
Humans can survive at high altitudes. However, if you go to a high altitude, your body needs to adjust properly by getting used to it slowly or you could get sick.
At 12,500 feet the air becomes thinner and oxygen becomes lower making it difficult to breathe.
High altitudes can cause low oxygen saturation levels or desaturation of an individual's blood. It happens because of low atmospheric pressure at high altitudes. Oxygen saturation levels refer to the extent hemoglobin is bound or saturated to oxygen.
