USC player pushed Kansas player into shooter

[All_Heart]

This was a play in the first couple of minutes of the second half in the KU / USC game.

A1 drives to the basket with an open layup. B1 pushes A2 into A1 and I think A1 made the basket. B1 is called for the foul and if I remember correctly A1 shot 1 free throw.

Is this right in High School or College?

The basket counts regardless because A1 had started the habitual try for goal. I would then think that Team A would get a throw-in on the endline or A2 would shoot bonus free throws if they are in the bonus. To recap B1 never touched A1.
