I have a board Node mcu 1.0(ESP8266 - 12E)
When I upload an empty sketch from arduino uno the compiler says :

Sketch uses 221999 bytes (21%) of program storage space. Maximum is 1044464 bytes.
Global variables use 31564 bytes (38%) of dynamic memory, leaving 50356 bytes for local variables. Maximum is 81,920 bytes.

Why this happen with an empty sketch without variables?

Because the uploaded file includes the whole operating system, where your sketch would only be some background task ...
