Stars maintain their spherical shape due to the balance between internal pressure pushing outward from nuclear fusion reactions in the core and gravity pulling inward. This equilibrium creates a stable equilibrium that keeps the star from collapsing under its own gravity and helps to maintain its rounded form.
The balance of forces that keeps a star from collapsing is called hydrostatic equilibrium. This equilibrium occurs when the outward pressure generated by nuclear fusion in the star's core balances the inward gravitational force trying to collapse the star. If these forces are not balanced, the star may either contract under gravity or expand until a new equilibrium is reached.
Nuclear fusion produces heat, and heat creates the pressure which keeps the star from collapsing under its own gravity. The relationship between heat and pressure in a gas is described by the Ideal Gas Laws. It also applies to plasma (which can be described as a super heated gas).
The sun's immense gravitational pull created by its mass keeps it from falling. The gravitational force pulls the sun's gases and radiation inward, creating a balance with the outward pressure caused by nuclear fusion reactions in its core. This balance keeps the sun stable and prevents it from collapsing under its own weight.

"While the star can produce energy, that keeps the star in balance - it keeps the star from collapsing. By the way, another outward force is the gas pressure, but that, by itself, is not enough to counteract the force of gravity in the case of a star."

The sun is held in place by its own gravity, which is balanced by the outward force of the nuclear fusion reactions happening in its core. This dynamic equilibrium keeps the sun stable and prevents it from collapsing or drifting away.
The uterus keeps the trachea from collapsing in a fetal pig.
inertia. because inertia keeps things going in a straight line, and that kind of throws it forward, but the direction of "foward" keeps changing as the car or roller coaster turns.
A star's gravity pulls all of its material inwards, preventing it from breaking apart. The force of gravity creates pressure in the core that counteracts the outward force of nuclear fusion, maintaining the star's structure and preventing it from collapsing or dispersing.
