 if mining is responsible for every transaction; what if it reaches the maximum amount of supply, how will the miners get paid?

[Welsh]

Through transactions. Miners process transactions by mining the block that your transactions are on. The fees people pay on top of the amount they send will go to the miners that are processing the block.
