If someone counters your spell, does it not count as being played for Ravenbloom Student or Abandoned Hall?

No — if a spell is countered, it does not count as being played for either Ravenbloom Student or Abandoned Hall.

Per Rule 425.1.b, a card that is countered is not considered to have been played. Both abilities trigger only when a spell successfully resolves — a countered spell never reaches that point, so neither trigger fires. Multiple FAQ rulings (#9548, #8945, #10782, etc.) consistently confirm this interaction.
