Won the game with two teamates but no points in Ranked

Hello!

I have a question on the point system for Ranked in season 16.

I won the game with no frag and no assist but still won the game with my two teamates.

And I got zero pts for this game (see the picture in attachment).

What is the system behind this please?

The game seemed weird since the last squads happened very soon.

Thank you very much!
