Yes, but not in a very useful way. TDS says that if you evaporate the
water, this is how much residue you'll have left. It doesn't say anything
about the contents of that residue.
It could be salts that make the water hard, or other salts that make the
water soft. There's a huge variation in the different minerals that get
dissolved in waters.
