You don't need us to tell you that comparing yourself to their success is pointless, so I won't.
What I will say is that this season of job hunting can feel like it will never end, but 5 years down the line when you've been working for a while, this will feel like no time at all.
If you're getting lots of interviews but failing after that, then it sounds like you've got a great CV and good at aptitude tests, but could work on your interview technique. A few suggestions:
Always write a thank you email and send it on the day of the interview. Google it for more detailed advice.
Make sure you present yourself well. This means in your appearance (professional and clean, controversial opinion but avoid anything too trendy) and in how you come across. You need to balance confidence with humility, so that you appear competent and eager to learn but not cocky.
Make sure you are actually answering the questions, and don't be afraid to ask them to repeat.
Give examples to back up your statements wherever possible, e.g. "yes I work really well in a team. When I was care worker I learnt that ensuring everyone had clear roles that matched their skillset was vital to working effectively, and carried that knowledge through to my final year assignment where I worked in a small team on xyz assignment...".
Always have questions! Make sure they are genuine (again Google for inspo) and have a few in case they answer one before you can ask.
