Yes, it is true.
In the relationship between volume and pressure when volume increases pressure decreases and when volume decreases pressure increases.
The volume decreases
as the pressure decreases the volume of gas increases at constant temperature
decreases
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.

Decreases.
As the volume decreases, the pressure increases, and as the volume increases, the pressure decreases, which constitutes an inverse relationship
This one is explained in Boyle's Law. It was stated that if the temperature is constant, the pressure is inversely proportional to the volume. Thus, if the pressure increases, the volume decreases. It is also the same as if the pressure decreases, the volume of the gas increases.
as the pressure decreases the volume of gas increases at constant temperature
Boyle's Law states that as the pressure of a gas increases, volume decreases so long as the temperature remains the same.
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
"When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases." More precisely, pressure is inversely proportional to volume.
If you increase the volume of the container, and not the gas itself, then the pressure decreases. If you increase the volume of the gas, and not the container, then the pressure increases.
