Is it profitable to stake ETH?

I've been hearing a lot about staking ETH, but I'm not entirely sure if it's a profitable move. Could you please explain to me the potential benefits of staking ETH? I'm particularly interested in understanding how the staking process works, the risks involved, and how much I could potentially earn from it. Is staking ETH a long-term investment strategy, or is it more suitable for short-term gains? Also, are there any specific requirements or qualifications needed to start staking ETH? I'd appreciate it if you could provide some clarity on these points.
