It will alter it--it will make the sphere heavier and less bouyant.
The pressure is irrelevant (unless it inflates the sphere to a
significantly greater volume). What a strange world you live in.

Actually the pressure is relavant, the more pressure technically
will make it heavier and therefore cause the "sinking at all"
I will admit..
(I incorrectly stated that. sorry)
but Can you prove that a 1 centimeter ball filled with air
at all will not float if it has a mass
of 1 gram?
1/2 gram aluminum sphere and 1/2 gram of air inside the aluminum ball.
or 3/4 aluminum and 1/4 air?
or 1/4 aluminum and 3/4 air?
1/2 gram plastic ball and 1/2 gram of air inside the ball.
carbon fibre etc..
lead?
Are you saying all of those will float or sink the same
amount because of the total mass only?

Yes.

How about the 3/4 gram sphere is filled with 1/2 gram of helium or hydrogen?
Do you really think the bouyancy of the mass type itself
makes no difference?

Yes. Total mass 1.25 g; volume unchanged--it's less bouyant than your
other balls. End of story.
