Not exactly operator. If you've ever been in tournament play, you can have floor judges (masters and experts don't need them)call such positions draws due to insufficient losing chances. Basically, the position is assessed and if a C rate player could draw against a grandmaster in the given position, than it is ruled a draw by tournament judges. If a pawn is added to one side, many times they will not rule it a draw.
A rook and king vs. a rook and king is considered by judges to be a drawn position (unless it was part of a combo which forced one of the rooks to be captured for free)
I also lost a game to Adamantine where he had an h pawn and king verses my king. I stood in front of the pawn and neither of us got anywhere. We just moved till my time ran out. This would be called a technical draw.
