The most advanced process is mostly only used for bleeding edge CPUs/SoCs. But over 50% of todays market is “mature process”; 65nm, 40nm and 28nm. It’s used for things like automotive sector, aerospace, analog ICs, power management chips, display drivers, microcontrollers, and sensors and pretty much any industry using ICs. Some fabs are currently expanding their 28nm capacity due to a lot of demand.
If TSMC is building a 5nm fab it’s because they’re seeing strong future demand for this node and comparatively it’s not that old by then.
