It is true that humans have notochords, however, this is true only when we are a developing embryo (we lose the this post-embryonic structure as adults). The notochord, being the stiff, supportive rod-like structure that it is, allows for us as vertebrates, to develop vertebrae. After the age of four, humans actually do have leftover PIECES of the notochord, which athletes may recognize as disks in between each vertebra within our spine.

it is a long rod-like support structure that runs along the back of the animals separating the nervous tissue from the gut. It provides a place for muscles to attach for ease of movement

They do not have a notochord.Notochords are unique to the phylum Chordata. Tunicates and amphioxus are chordates that have no notochord. They are the two exceptions.

How to get chordoma?
A chordoma is a rare type of cancer that develops from the notochord. The notochord forms the early spine in a foetus as it develops inside the womb. After about six months, most of the notochord is replaced by the bones of the spine. However, small amounts of the notochord may remain, and these can sometimes develop into a chordoma.
Is an animal with a backbone and gills but no notochord still a chordate?
The notochord is a flexible rod found in the embryos of all chordates, and is replaced later in life by the vertebral column and the main axial support of the body. If the animal you are referring to is an adult and lacking a "true notochord", it is still a chordate because the notochord has simply transformed into other parts of the body. However, if it is still an embryo and STILL has no notochord, it is not a true chordate.
