Answer:
Hey mate! Here's your answer.
We do not fill up the balloons with helium.
If we talk about the gas balloons, then they are filled with helium as people use helium tanks to fill up them. But when we blow a balloon naturally with our mouth, then we fill it just with normal air. The one that is present inside our body.
Yes, there maybe a small amount of helium in the air that we use to blow up a balloon with our mouth but in a very small amount.
Hope you find this helpful! I'm not sure if it is correct completely but part of it should be correct.
