Conceptual doubt regarding esp32

Well, I have some very beginning questions regarding esp-32, since I need to document everything.

I have a DOIT esp-32 card, with the esp-wroom-32 module. I saw that the base chip is ESP32-D0WDQ6.

Well, esp-wroom-32 would just be the module, encapsulation, right? the microcontroller itself would be the existing chip inside, right? Does this chip already have everything integrated, like wifi or is it placed in the circuit at the time of encapsulation?

I know they seem like obvious questions, but for me it wasn’t clear in the documentation
