Not correct. There are some proposed standards that could take place in the future but you can buy an electric hot water heater today that is greater than 50 gallons and doesn't use a heat pump.

Such as: Jacuzzi type tub cannot be filled with hot enough water? People need to take showers in succession or parallel? Running out of hot water for several things operating at the same time? Tired of the water cooling off during a shower.
So they decide to get a bigger tank to alleviate some of those issues. If they pick a tank >50 gallons, then federal regulations kick in that mandate a more efficient tank with increased insulation and using a heat pump system. The cost for that tank is much higher than a tankless heater (double or more). It is also a lot bigger and might not fit in an existing location.
So in that case, the answer is clearly "yes"; a tankless is the better choice since initial cost would be significantly lower.
