I get job offers from companies I don’t want, but I fail to get accepted by the companies I prefer.

Yesterday, I had my interview to the company that I really want. I passed their assessment but I have this feeling that I will not get the job offer because I don't feel like I gave my best to the interview. Then earlier I had an interview with another company and the interview went well. I feel like I will get the job offer and damk after 2hrs I got two emails first from the company that I really like it says that they will proceed to another candidate and I didn't pass the interview then the second email that I got is a congratulatory email from the company I don't like it says that I passed the interview and for job offer.
