I got hired then today It got taken off me

Im not taking it personally , they loved my application , I had an lot of experience because Ive had jobs as an teenager , It was on zoom , I had the interview last week and I had been hired to teach horse back riding for an 3 month summer job , I had been riding since I was 10. My family own an farm too with horses on it which they sold. I got an email instructing me to book an staff zoom meeting to ask questions about the job , I did. This was last week. Yesterday , I had my meeting. I booked as early as possible to show I was serious about my role , I didnt have many because I did an lot of research on their website , I politely told them this , They told me some imformation I needed to know then said they would email me soon with instructions on what to bring with me ,then earlier today I seen an email saying Im not quiet right for the job , they never said why only stated I would be successful getting hired by someone else because of my experience and skills with special needs kids and horse back riding. That is all the information I had recieved.
