What is the difference between them?

X-ray is shooting rays through the body to see what’s inside in one or two projections. CT is the same rays but shot multiple times (like dozens or hundreds) from different directions to construct a 3D picture. MRI is using magnets to excite atoms in the body in specific ways to also construct a 3D picture. MRI differs from CT in that it doesn’t involve potentially dangerous radiation, and also the kind of body structures and anomalies that can be seen in CT and MRI are somewhat different.
