It's not true either way. Very little is actually practical, it's just that when something looks good people think it is practical because they want to believe that.

Marketing feeds into this and tells people movies were done all practical or made "heavy use of practical effects" and it's just lies.

This is 5 part series.

Even before this people were saying stuff like mad max was done "almost all practical" because they saw behind the scenes stuff of flipping a few cars even though the movie is wall to wall digital effects. Sometimes the elaborate "practical effects" don't even move right and are used for reference and completely replaced.
