Hmmm, ok I got the main difference that nodes are what validates the transactions while miners are those who create new blocks and insert this validated transaction in these new blocks, and in return, these miners get block rewards and also fee rewards then what those nodes are getting? I mean I thought miners are the ones who validate the transaction as I thought validation is one of the main components that miners do and all miners do but according to your definition.

One person X runs a node, and validates the transaction, right? and the second person Y (miner) can create a new block and can add this validated transaction coming from X to this block. So what these validators are earning? I am this old to know the difference (haha) so I hope you won't mind me.
