Generally, yes. Usually there are settings for how much regen you want, but the term 1 pedal usually inies a regenerative brake strong enough to stop at stop signs or when exiting freeways.
"1 pedal" just refers to vehicles that perform a high degree of regen when the throttle is lifted. Other designs that require the user to press the brake pedal are not necessarily engaging the brake pads when you do so, many of them are also slowing the vehicle with regen when you press the brake pedal.
When you press the brakes on an EVs or hybrid, they typically use regenerative braking up to the limits of the motor and charging system, and only apply the brake pads after those technical limits are met. There are many "two pedal" vehicles that can come to a complete stop, or close to it, with regen.
