[Python] random variable match/case [duplicate]

I tried to make a secret number game, but with 4 correct numbers using match/case statement like this:

import random
secret_num = random.randint(1,20)
secret_num2 = random.randint(1,20)
secret_num3 = random.randint(1,20)
secret_num4 = random.randint(1,20)
num = int(input("Enter a number between 1 and 20 : "))
match num:
case secret_num | secret_num2 | secret_num3 | secret_num4:
print("You won!")
case _:
print("You lost!")


but it didn't work, I am a beginner and GPT-5's explanation was weird, he said that Python thinks that you are making a new variable in the match/case statement or something. I will be very thankful to anyone who answers in a simple way.

I wanted this to happen :

Enter a number between 1 and 20 : 5
You won!
Enter a number between 1 and 20 : 7
You won!
Enter a number between 1 and 20 : 8
You won!
Enter a number between 1 and 20 : 17
You won!


4 correct numbers, and the rest are wrong.
