This is false. Traditionally, when only one chamber of Congress passes a bill, headlines explicitly state which chamber. "The House passed a bill that..." or "The Senate passes a bill that..."

The OP is correct that Congress implies both chambers. Yes, "Congressman" or "Congresswoman" refers to House members. But the headline says "Congress".

It’s not false and I already explained why. You choose to ignore the social usage.
