When should I use manual camera settings instead of auto modes?

I'm new to digital photography and using a Canon EOS T3. I've been getting decent results in full auto, so I'm trying to understand when manual control actually makes a noticeable difference.
How much better can manual settings be compared with automatic modes? Is the camera usually smart enough to choose the best exposure on its own, or are there situations where manual is clearly better?
I'm also unsure how often settings need to be changed. Do you adjust exposure for every shot, or mainly when the light changes? For example, if I'm photographing in the same forest for an hour on a sunny afternoon, would I usually keep one exposure setup, or keep changing it from shot to shot?

Applying manual controls allows one more freedom to enhance, manipulate and master applied photographic applications. By understanding the interaction of shutter speed, aperture, and ISO speed, photography — identified as "drawing with light" — can be utilized to its fullest potential.
Full creativity with the use of manual control can then be used to make those "How did they do that?" photos.

Auto modes often work well, especially when you're starting out. But manual control matters when you want a specific result or when the camera meter is easily fooled.
Examples where manual helps:
- controlling depth of field, such as blurring the background
- choosing a shutter speed fast enough to freeze action
- keeping exposure consistent across many shots
- shooting in lighting that stays fairly constant, but where bright/dark subjects confuse the meter
A good example is indoor sports: if the light is even, auto exposure may change from shot to shot because of dark uniforms, glare, or different backgrounds. In manual, you set exposure once for the light and get more consistent results.
You usually adjust settings when the light changes, not necessarily for every subject. If you're in the same lighting environment, one exposure may work for many shots. If you move into shade, direct sun, or a different indoor area, you may need to change it.
So manual is not always “better” than auto, but it gives you control, consistency, and creative choice when auto can't know your intent.
