printf function changes int to char when using format specifier?

[vlsidesign]

Example
printf("I have %d cars. \n", 10);

Is it more correct to say that the printf function doesn't insert the
integer, rather into changes the integer into chars and then inserts
it?

Neither resembles something that is correct.

man printf()

printf inserts (into the stdout output stream) a textual representation of the
int value 10.

It doesn't change the integer into anything; 10 is still an integer. Rather, it
computes a sequence of characters {'1', '0'} from the integer.
