this changes a lot.
every 3 secs a block is produced and the rewards are split by activity on the chain.
100K would be your share.
if no one else did anything you would get all the rewards which is greater than $1 but if a bunch of dormant accounts decide to be active again. it could be much lower.

You really need to sit down and chat with someone.
your questions are very basic like you don't understand how the chain works at all.
