Xbox game pass ultimate

Hi can anyone tell me what happens to my one year of gold because I bought the $1 for one month ultimate and then my gold sayed that it expired and then I see the ultimate subscription that says renews next year on July 2021 (which my gold was going to
expire on) and I am also confused if im now going to need to pay $14.99 for the ultimate every month once It expires.

Can my gold subscription I had on it for one year come back if I cancel the ultimate subscription or am I going to need to buy a new gold card.

Btw again also confused that it says next year they will charge me $14.99 on july but does that mean I have ultimate for this year free with gold until it expires (on my gold date) or am I going to still need to pay next month for the ultimate.. ??

:)
