Why do confirmations grow for every transaction in Bitcoin?

Question

bitcoin

Forgive me for the stupid question, but I want to understand why the confirmations of each transaction grow?
For example, I made a transaction three years ago, and the number of confirmations grew to 300,000 and continues to grow.
Are these confirmations rewarded to miners or is it a counter that counts only in ancestor blocks?

Answer 1

This is the counter of blocks that have passed since the operation.
