Why can't a particle in a container have zero energy?

Is it because that the zero-point energy is already E1?

According to the website, "Fermilab Today," at the quantum scale, space never has zero energy because electrons have both particle-like and wave-like properties. Their constant movement can be measured in kinetic energy. From my understanding, I think a particle in a container cannot have zero energy due to its particle-like and wave-like functions.

I think it's also because the lowest possible energy level is n=1, which by default means that the electron has energy. Also, a particle with no energy means that it s completely motionless, which is impossible.
