In general it is considered good to make lots of small commits, a commit is a bundle of changes you send to the shared project, you want to keep them small so they are easy to integrate and debug (if necessary).

But just counting them is a dumb way to judge productivity, and every programmer hates it.

The way to become a manager at a tech company is to be good at programming for a long time, an extremely specialized skill set that has nothing to do with management.
