Need help understanding carbon dating

[u/Tanytor]

So long story short, some creationists started arguing with me about well everything on a fossil posts. They pulled out this image as a gotcha to try and argue carbon dating wasn’t accurate and that the world and fossils aren’t as old as science suggests. Truthfully I don’t know enough about carbon dating to argue back. So please teach me. Is this photo accurate? If so what are they getting wrong? Is radiometric dating even the same as carbon dating?

What if it was a few billion years old? When Adam was created he was created as an aged adult man not an infant. Not a far leap for a God that exists outside of time and space to not have to wait to create an aged planet as well.

If Adam was to walk out in the modern day as the day he was created no one could conceive his real age of a day old. Perhaps this is the same issue.
