Helium is scarce in much the same way that crude oil is scarce: there are plenty of reserves still in the ground, but we are consuming them orders of magnitude faster than they were produced, and as the reserves dwindle the costs of extraction will rise.
Helium is a chemical element, and aside from nuclear reactions (which are economically infeasible for non-microscopic quantities) we can't produce more of it.
