Actually, if you are doing like you wrote, you’ll be executing an application.

Take a look at the following documentation to help you clarify your mind.

Applications:

Dialplan functions have the following basic syntax:
FUNCTION_NAME(argument)
You reference a function’s name the same way as a variable’s name, but you reference a
function’s value with the addition of a dollar sign, an opening curly brace, and a closing
curly brace:
${FUNCTION_NAME(argument)}
Functions can also encapsulate other functions, like so:
${FUNCTION_NAME(${FUNCTION_NAME(argument)})}

Example:
exten => 123,1,NoOp()
same => n,Set(TEST=example)
same => n,Playback(silence/1)
same => n,SayNumber(${LEN(${TEST})})
