It's a phased array, it uses those many little chips to do "beam steering". Check out this video by The Signal Path (a Bell Labs expert!) doing a teardown and explaning parts of it: [this video]

There’s a pretty crazy amount of electronics in the dish. They are likely selling it at well below cost at present. Teardown showing PCB at: [LINK] And more detailed RF analysis at [this video]

Starlink receivers are actually very complicated. They make use of a bunch of high-end FPGAs and a bunch of other expensive and uncommon components. See this teardown: [this video] .
