For any object, the summation of its potential and kinetic energies is constant.
Total energy.
The mechanical energy of the ball is conserved as it falls freely in a vacuum, meaning the sum of its potential and kinetic energy remains constant. Additionally, the total momentum of the ball is conserved during its free fall.
The sum of potential and kinetic energy is called "mechanical energy". This is NOT conserved, though - unless you consider the microscopic scale, in which case (for example) heat energy is a type of kinetic energy. In this case, the sum is simply the total energy, and the total energy IS conserved.
Mechanical energy is always conserved in a closed system. It can exist as potential energy (stored energy) and kinetic energy (energy of motion). This conservation principle is known as the law of conservation of mechanical energy.
Mechanical energy is equal to potential energy plus kinetic energy in a closed system. The total mechanical energy is conserved.

Kinetic energy cannot exceed potential energy because the total mechanical energy of a system is conserved. When an object gains kinetic energy, it does so at the expense of potential energy, and vice versa. This conservation principle ensures that the sum of kinetic and potential energy remains constant in a closed system.
Potential energy of an object due to its motion and position with respect to gravity. It is conserved in a closed system where only conservative forces are at play.
