Very specific question about withdraws and contributions

So let’s say I make 200 dollars in gains on shares in my Roth IRA and I sell for a total of 400.

In this situation let’s say I have contributed a total of 1k can I withdrawl the 200 in profit like that SPECIFIC money that came from the profit because it’s still under the 1k contribution?

Or does the money I withdrawl have to literally be the specific funds that I have contributed. Sorry if I didn’t explain this well. I’m hoping people know what I mean lol.

Like the gain dollars vs the contribution dollars does that matter? So if it’s 200 dollars in gains can I withdrawl those specific dollars when it’s still within the amount I contributed
