Why should it squirt out? Who would want that? Think about basics:
Pressure is force divided by area.
The weight of the ball (downward force) equals the upward force from the water pressure, then it can float.
You want the water pressure to be about 1 bar (equal the air), so it does not squirt out.
From that you get: weight of the ball divided by the partial area of the ball that is in the water equals 1 bar.
That’s how big and how heavy your ball must be, then it works.
