So I ran
netstat -s in the process of learning and actually looked through the output and found something rather puzzling: for tcp, the number of "connection accepts" is a little more than the number of "connection requests".
How can this be possible? How can a system accept more connections than were requested?? I could upload a screenshot of my terminal, but I found the next best thing: a link from IBM where the same thing can be noticed in sample output and another documentation page with example output if you please just Ctrl+F for accepts, it's in only one place on the page.
