i saw somewhere that i need a usb host to connect my usb keyboard to esp32 board because esp32 board does not understand usb connections

Yep! ESP32-S2/S3 can handle USB connections all by themselves, no extra stuff needed (ref). For other ESP32s, you've got two choices: either add a USB Host controller module or use a software implementation on GPIOs. In this project, we've gone with the software option, using the ESP32 USB Soft Host Arduino library.
