A human-powered vehicle control device includes an acquisition unit, a first electronic controller, an operation probability output model and a second electronic controller. The acquisition unit is configured to acquire input information related to traveling of a human-powered vehicle. The first electronic controller is configured to decide control data of a device provided at the human-powered vehicle in accordance with a predetermined control algorithm based on the input information acquired and performs automatic control on the device by the control data decided. The operation probability output model outputs a probability of a rider performing an intervening operation on automatic control of the device based on the input information. The second electronic controller is configured to change a parameter for deciding the control data in a case where a probability that is output from the operation probability output model is equal to or more than a predetermined value.
