Indeed. Same with the 'Draw by 3 move repetition' rule. The site doesn't claim the draw automatically, you have to click the 'claim draw' button.

However, if only the Kings are left, it is an automatic draw because it is what is known as a 'Dead Position'. Neither side can checkmate even if the opponent make the worst possible moves, and the game ends immediately.
For the official wordings, go to the 'Laws of Chess' at : -

and read articles 5.2d & 9.2 for position repeated; and 5.2b & 9.6 for
a 'Dead Position'.
