Yes, but most things larger than atoms and molecules behave essentially as classical objects in practice because quantum coherence does not generally extend above these scales. A big reason for this is that constant interactions with the environment act as a form of continual measurement process so it is like the wave function keeps getting collapsed, and this is especially true of systems as they get warmer (which is why quantum computers generally have to be kept so cold to have any hope of working).
I’d make a friendly amendment here that “quantum” really isn’t an “object” but intangible attributes/properties that manifest in our physical reality, such DNA as the code for biologic systems.

Humans are literally made from quantum objects.

I strongly disagree that this is a widely held, and therefore useful, definition of this term, especially if somehow DNA has gotten involved in this.
