Why is byte NOT a type?

I don’t get it at all !

It is one. Defined if Arduino.h is included, as an alias for uint8_t, unsigned 8-bit.

          #define _NOP() do { __asm__ volatile ("nop"); } while (0)
          #endif
          
          typedef unsigned int word;
          
          #define bit(b) (1UL << (b))
          
          typedef bool boolean;
          typedef uint8_t byte;
          
          void init(void);
          void initVariant(void);
          
          int atexit(void (*func)()) __attribute__((weak));
          
          void pinMode(uint8_t pin, uint8_t mode);
          void digitalWrite(uint8_t pin, uint8_t val);
          int digitalRead(uint8_t pin);
          int analogRead(uint8_t pin);
