@Pazcha99 I have taught on Access for over 10 years.
If you have been told to 'Pass your access course overall with a minimum of 45 credits at Level 3' means that you require at least passes on all of your assignments. Most programs are made up of 3 subjects referred to as modules with 5 assignments for each which for instance means, 'Sociology - 5 assignments worth 15 credits in total' Psychology - 5 assignments worth 15 credits in total' Criminology - 5 assignments worth 15 credits in total' - as each assignment is worth 3 credits.
Being told to just pass the course is quite rare, although it does happen, particularly if they are looking for evidence of recent study and you already have A levels, a degree or a masters already.
In most instances, you will be given a UCAS tariff target of something like 109 points, which is achieved by a combination of grades. As the other poster highlights there is a calculator on the UCAS website which lets you know what points you get from your grades.
Some areas such as Nursing require a good GCSE English and Maths grade too, Midwifery needs the science GCSE too in most instances.
If in any doubt, speak to the admissions tutor for the University/ies that interest you
NB: "the uni told me that ucas points doesn’t matter when it comes to access courses" - it really does, but you might have been made an unconditional offer and missunderstood
