That is how I understand it, yes.

This is a 'high level' ruling, which unlocks the 'deadlock' on the cases about the legality (or otherwise) of biometric collection via Aadhar for specific government schemes.

The Attorney General's argument that citizens have no fundamental right to privacy has been invalidated/overruled/whatever-the-correct-legal-term-is, by the constitutional bench. He (and his team) have to find new arguments now. [1]

The lawyers of both sides on those cases, now have to proceed on the assumption that privacy is a fundamental right. The pro-govt (so pro -aadhar) side will likely argue for 'reasonable restrictions' on the right. The anti govt side will likely argue that such restrictions are not 'reasonable' and that aadhar violates fundamental rights (or so my lawyer friends tell me [2]).

[1] Tangential: The AG who made that argument has retired, and there is a new AG who will appear for the government.

[2] They are probably oversimplifying, so I can get the gist, the same way I would if I had to explain some complex programming to them. I'm not a lawyer. :-)
