It's all the same helium, of course, going through different levels of industrial purification. I only clarify this as it isn't like we find super pure reserves in nature and that's what is lucrative, but instead it's all the same contaminated helium and then it gets processed to further and further levels of purification, like many other industrial products.

If there is a shortage of helium, it's a shortage of all the same helium. But so long as it's treated as a novelty gas, and so long as it continues to just be wasted, it's hard to take claims of a shortage too seriously.

As a fun fact, the vast majority of helium on Earth is courtesy of the radioactive alpha decay chain starting from heavy elements like Uranium and Thorium. Helium got trapped by the same geological formations that trapped natural gas, hence why they're usually found together despite being from completely different processes.
