yep

Case Book 4.15.4 C, supports the concept that the violation occurs when (because) the ballhandler is first to touch the ball.

This case deals with throwing the ball off the opponent's backboard or an official, not pushing it to the floor.

Case Book 4.15.4 D, (c) and (d), seem to equate catching the ball with fumbling the ball. And that seems to be consistent with Rule Book 9-5-3, and Case Book 9.5 (b) and (c).

A fumble can occur at any time, but read the definition of a fumble. It includes the phrase "loss of player control". A dribble cannot occur when a player is not in control.
