Pressurized tennis balls contain gas (usually nitrogen) in the ball's center. For some balls, there's a mixture of air and nitrogen to give different bounce. If you've ever seen tennis balls sold in bulk in large bags, those are not pressurized, but pressureless.
Why do tennis balls have nitrogen?
There is a thin layer of adhesive on the rubber. Pressurized tennis balls are filled with either air or nitrogen, with nitrogen keeping the balls inflated longer. On the other hand, non-pressurized balls are solid, which keeps them from deflating.

How do they get air in a tennis ball?
The half-shells are placed in a hydraulic press, with the ambient air pressurized at 18 psi. As the shells are combined into a tennis ball core, the pressurized air is trapped inside. Once the adhesive cures, the shells are cooled to at least 127 degrees Fahrenheit to prevent the core from exploding.
