The theory here is that the cabal has been breeding a certain person for a certain mission for hundreds and possibly thousands of years with arranged marriages and coupling together of specific genetic lines to meet their objective. The bloodlines of Diana and Charles were likely brought together for a specific reason and the circumstances surrounding their first born and his preparation since birth for something (under the guise of becoming King of England/UK) are interesting.

We know that the cabal's religion involves both worship of the sun and the moon, and that they pay very close attention to dates and number symbology. There may be some Gematria associated as well.

Unconfirmed is that he became the 1000th 'Knight of the Round Table' at age 22.

TDLR: Is it possible that he is being groomed not to be the King of England/UK, but of the World?

Solar Eclipse of June 21, 1982: https://infogalactic.com/info/Solar_eclipse_of_June_21,_1982

The odds of Prince William or anyone else in a line of succession being randomly born on a day that is both the Summer Solstice AND under a solar eclipse are staggeringly miniscule. Indicating that this was was a planned event arranged to coincide with that particular date. EDIT: added "in a line of succession" which was intent of the statement. Commenters have pointed out that there were likely a few million people born on that day. It looks like it might be about ~20 million people worldwide born on a single day in 1982.
