Centrifugal force is the force that moves things away from the center as much as possible when they rotate. In addition, the earth also exerts a gravitational force opposite to the centrifugal force. Gravitational force is the force that pulls things toward each other.
In other words, everything on the earth is subject to both centrifugal force, which pulls it outward, and gravitational force, which pulls it toward the earth.
After subtracting the centrifugal force from the gravitational force, the remaining force is called gravity, which pulls things toward the earth. This is why people, things, and ocean water on the earth do not fly out of the earth.
