Question about NA Group Stage

For group stage is the ranking dependent on round wins or actual won games. It seems like their points are just based off the rounds that they won in total? Anybody able to explain?

It's by the count of won games first and if the number is tied it comes down to round differential.

It's sorted by matches won with rounds won as the tiebreaker.
Since everyone has only played one match so far its sorted by rounds for top 3 and bottom 3.

Just think of it like this:
1 win = 1 point
The RF/RA is for finding out who stays higher during a tiebreaker when teams have the same amount of points

Games won and then round deficit if i'm not wrong
