No, Josephine I thought someone had explained it upthread.
The "King" is the monarch.
The "Queen" can be either a female monarch or a consort.
This comes from the days when women were subservient to their husbands. If a man married the Queen, he had a very good chance of styling himself as King. Mary Queen of Scots' useless tosser of a husband, Darnley tried this, and didn't get very far as by then she and everyone else had seen his true colours. The Earl of Bothwell raped Mary in an attempt to get her pregnant so she would have to marry him and he could proclaim himself King. (This is sometimes portrayed as a love affair between them and it is not at all clear what did happen, but it was probably as I have said and she had to pretend not to have been raped in order to maintain some semblance of power and control
)
Mary Tudor married King Philip of Spain who called himself King of England, to the people's dismay. Luckily he lost interest in Mary and did not pursue it too much but I think he also tried to marry Elizabeth when Mary died. Elizabeth knew that the only way to not have some bloke muscling in on the act trying to make himself King was not to marry at all.
When Victoria came to the throne she was very young, so things had to be worked out very carefully so that she married someone who would not try to take over. Prince Albert was perfect, he did a lot of the work, but SHE was the monarch. Prince Philip has been similar.
