Education only, not investment advice. The answer comes from the numbers you typed in, not from your account or the market. Simulated results are hypothetical and have limits: real trading has slippage, gaps, changing results and emotions. Trading leveraged products can lose money quickly, including all of it. Risk warning

The gain is capped, the loss is not
A short sale makes money when the price falls, and the most it can make is the price itself, if the stock goes to zero. A rise has no ceiling: a stock that doubles costs the short its whole sale value, and it can go on rising. On top of that the borrow fee runs every day the trade is open, and any dividend paid while you are short comes out of your account.
Most brokers also want margin on a short and can ask for more cash as the price rises; see the margin call calculator. For a plain buy and sell, use the stock profit calculator.
Not advice or tax advice. Arithmetic on the numbers you type; margin interest and local tax rules are left out.
