A giant part of Mozart’s genius came from his early exposure to just monumental amounts of music. As it turns out, giving a child perfect pitch and training them to play the violin before they can read the alphabet are rather mechanical endeavors that we can now do pretty reliably given a very early start, the money to pay for the programs, many of which aren’t super expensive, and access to venues that will make that child’s abilities useful. It has little to do with proclivity or genetics. Some will take to it quicker than others, but most kids can do this.

The fact is that most such child prodigies do not go on to be master composers or even professional violinists, but those that do have a huge head start on mastering what would normally take someone until much later in life to pull off.
