Getting error when comparing list item int and integer

Question

The line Where I'm getting the error "TypeError: 'int' object is not subscriptable" is marked with a bunch of !!!! in the code I think the same is happening further on in the code aswell.

I tried with empty lists like endCoin = [] and a few other things but I couldn't find anything that worked for me searching so I've posted here

from random import randint

coins = int(input("Enter how many coins you have: "))
buyin = int(input("Enter stake buyin price: "))
winrate = int(input("Enter your winrate: "))
trophyCurrent = int(input("Enter how many trophies you have right now: "))
trophyRequired = int(input("Enter how many trophies you need for ring: "))
trophyMinus = int(input("Enter how many trophies you lose: "))
trophyPlus = int(input("Enter how many trophies you win: "))
gameCount = 0
endCoin = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
endTrophyCurrent = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
endGameCount = [0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
averageC = 0
averageT = 0
averageG = 0
repeatTimes = 10

# Get the average amount of games it will take to win a trophy and estimate likelihood of losing all coins
for i in range(0, repeatTimes):
    endCoin[i] = coins
    endTrophyCurrent = trophyCurrent
    endGameCount = gameCount
    while endCoin[i] >= buyin and endTrophyCurrent[i] <= trophyRequired: #!!!!!!!!!!
        gameOutcome = randint(0, 100)
        if gameOutcome >= winrate:
            endCoin[i] += buyin
            endTrophyCurrent[i] += trophyPlus
        elif gameOutcome < winrate:
            endCoin[i] -= buyin
            endTrophyCurrent[i] -= trophyMinus
        endGameCount[i] += 1```
