What is the difference between animators and animators- What is the difference between an Animator and an Animation?

problem ：

It looks like both Animations and Animators allow me to animate properties (position, opacity, scale, rotation, etc) on objects, and I'm having a hard time differentiating between the use case for both. look , Animation and Animator all Allow me to attribute on object （ Location , The opacity , The proportion , Spin, etc ） Animate , And it's hard for me to distinguish these two use cases .When should I use an animator versus an animation and vice versa? When should animators be used instead of animations , vice versa ？
