I just vibe-coded the first project in my life, can anyone tell me what is going on here?

First off, I am a history major, so I don't really have any knowledge or background in LLMs or what you guys call an AI Agent. But I have always been interested in the field and have lots of free time this summer.

I am, though, very good at using AI chatbots, like chatgpt, or Gemini, becasue I relied on them a lot while writing papers. This time, I wanted to use them for programming instead. I wasn't sure which AI coding tool to use for someone like me, so I simply picked a random one. Now, jumping to my question(please check the image I attached below):

I built a leaderboard for the 2022 World Cup tournament. TBH, it looks good and is structured well, but I can see many mistakes or errors, such as: Bruno's picture is a stadium, or Messi's picture is on Van Dijk's name. I think the issue was that my prompts weren't clear enough. What strategies do you guys use to improve the quality of vibe coding? So basically, what main components do you guys normally consider putting in to make AI understand what you want to build?
