Yeah only a top down angle will give the exact reading. They've figured out that a tiny bit of the ball is inside the line.
Also for this WC they have sensors inside the ball which they might have used for this.

Same for tennis too. The ball needs to be only a fraction touching the line to be called IN.  All other parts of the ball can be clearly outside the line.

But do FIFA have that technology used in tennis ?
