in order to mine bitcoin you will need special equipment which is called ASIC. you need to buy them and set it up to mine bitcoin, then you connect to a pool to share the work and try finding a block to share the reward.
as for your wallet, you now have a bitcoin address. you can give this address to others so that they can send you bitcoin. the address starts with 1, 3 or bc1. your private keys are obviously private and you should keep them that way. make sure to back up your seed also by writing it on a piece of paper and storing it in a safe place out of sight.
also it is good to read this:
