If you are not interested in or good at math, learning big data may bring some challenges. However, if you are interested in data analysis, data mining, and machine learning, and are willing to make efforts, it is entirely possible to learn big data. If you need help, you can ask for help, such as taking an online course or consulting a teacher.
As for English, mastering this language is very helpful for learning big data, because many related documents and resources are in English. The development of foreign programming is relatively early, so many problems you encounter can be found in the external network or related literature, but there are not so many resources in China.
