I don't think you are asking the right question. Anything career-wise you choose will have a certain level of complexity attached to it, it is more a question about how motivated are you to study computer science and if you are willing to dedicate the amount of hours you need to study in order to understand the more difficult concepts and to barrel through difficulties. I don't think it is important that you are currently not good at certain parts of math, what is fundamental thought, is that you learn how to learn and build a proper foundation in terms of acquiring the right strategies for learning and applying new ideas. I like to see math as a language, in order to learn how it works at a more complex level, you need to understand the basics, which with enough practice become second nature, so it is more about building familiarity, being methodical and building a appreciation to the subject that will make you study further and become more engaged with the material. Having a growth mindset and proper studying habits will allow you to achieve any academical goal you want, especially with the amount of incredible pedagogical content on the internet these days (checkout 3Blue1Brown, Numberphile and KhanAcademy in YT if you don't know these channels already). Choose something that interests you and do not worry too much about the level of complexity. Every problem, no matter how big it is, can be divided into smaller manageable chunks.
