Looks like he's used a different board declaration for the "pinouts".

Is A1 a GPIO37? Or tell me what type of ESP32 board you are using. Thank you

When I was testing I was using the Adafruit ESP32 Feather(as the board selected in the IDE). However, that analog pin is just for "random" use, so any unconnected analog pin will work.
