Does prayers from atheists have more or less "power"?

I had a friend have something bad happend, so I wanted to help. But as we knew eachother online, I didnt know how to help, and since they asked, I prayed. I dont really know how, and I didnt aim it at anyone particular.But it made me curious. Would a higher power care about a prayer from an atheist?Anyways, that you for your time and have a good day.
