I don't think a level stats/maths should be compulsory (as someone who absolutely loves maths).
One of my reasons is that the subject teaches many different concepts and theories, but they aren't modernised/taught in a modern way to successfully equip students with the skills needed for a technology-driven and progressive world. And because of this, many students feel maths doesn't have any relevance in this world, which I feel isn't true. Moreover, a lot of these concepts/theories (at least at gcse level) aren't really connected with eachother, which means that although maths builds up on a foundation knowledge, the individual concepts are laid out as stand-alone concepts rather than being laid out in connection to real-life concepts.
I also think that the teaching of maths should be better adapted to individual learning styles from an early age, especially primary school/early secondary which is an important time for cognitive development. For example, being able to use maths concepts in everyday activities like making crafts or through actually being active can help encourage enthusiasm in the subject. I've seen that in relation to other subjects at primary/early secondary, maths seems to be the one that is hugely theoretical and doesn't really give room for creativity - like in english there's creative writing, in science there are experiments and in geography you get to learn about real life issues that affect us. If maths was taught in a more engaging way, people might enjoy it more and develop a love for it rather than being stressed with not understanding it.
But there will always be students who dislike maths and that's fine. I think that by the time students finish gcses they will have a better understanding of which subjects they enjoy/don't enjoy and which subjects they want to pursue and it's best to let them do that and figure out what they want to do.
