The Espressif chips are available as cheap modules, and frequently used as such.
People generally refer to the module, not the isolated chip. The modules are effectively like a chip that you solder to the board.
Modules are "just" chip + all necessary hardware to start + antenna connector/pcb antenna. Those modules don't add any functionality to the chip.
The main benefit of those modules is: it's already certified with FCC and others, so you don't have to re-certify your design for radio communication. Since RP2040 does not have a radio, this is unnecessary.

What part of that contradicts my comment?
To be clear, GP is the one saying the ESP32 is more than just the chip itself, complete with battery controller and camera connector.
