pulling a variable from text file in a sentence - batch-file

Question

im currently making something along the lines of a sentence generator, it uses text files which have a list of words in them, for example celebrity.txt has a list of celebrities and this script both shuffles the text file into newcelebrity.txt and takes the first one from that list so its different every time, and ive run into a problem, i want it to be one line and that you can call a variable in the sentance youre typing, not break it down as it is right now, is there a way to have it "this $celebrity is really great" as of now, it works like this: https://gyazo.com/9ae8583ed5457709bd1c1dc9cc0cc106 and outputs as this https://gyazo.com/1a5a90f1fbf80faa73d71791a8c1c761, i dont mind the quotation marks at all, its just the way you input it.
Is there any way to make it work like i want it to or is this a limitation of batch files?
set /p message=Unity:
set /p input=The variable:
set /p after=Unity:
:gen
setlocal
cd ..
cd rcs
echo doing background work, please wait a few seconds :)
for /f "delims=" %%a in (%input%.txt) do call set "$$%%random%%=%%a"
(for /f "tokens=1,* delims==" %%a in ('set $$') do echo(%%b)>new%input%.txt
endlocal
cls
set "File=C:\Users\%USERNAME%\Desktop\gg\rcs\new%input%.txt"
set /a count=0
echo background work done :)
timeout /t 1 >nul
SETLOCAL enabledelayedexpansion
for /F "tokens=* delims=" %%a in ('Type "%File%"') do (
Set /a count+=1
Set "output[!count!]=%%a"
)
For /L %%i in (1,1,%Count%) Do (
Call :Action "!output[%%i]!"
pause
)
Exit

To get rid of the quotation marks, just use %~1 instead of %1.
I'm assuming, you want to input something like 'this $celeb is great' instead of the first three set /p lines (as your output is already in one line).
I used some fixed variables to keep it short - of course you would fetch them from the user and the text file instead, as you already did.
#echo off
setlocal EnableDelayedExpansion
set "count=3"
set "output[3]=John"
set "sentence=this $celeb is great."
REM above would be your 'set /p' instead
call :action "!output[%count%]!"
goto :of
:action
echo !sentence:$celeb=%~1!
(just to be clear: $celeb is not a variable - it's just a string, that we replace later, so from user's perspective, it behaves like a variable)
