It doesn't matter if you're bad at math. It doesn't matter if you're bad with technology. Everyone starts from a different place, but they all get where they're going eventually.
A thing I heeard a lot at university was that in the first year, there was a small difference in ability between the kids that started learning to program in middle/high school, and the kids that started with their first university course. By the end of year 4, there is no difference, the distribution of proficiency is pretty much entirely uncorrelated with where they started 4 years prior.
The point being, it doesn't matter if you never learned your multiplication tables and this is the first time you've ever touched a computer. If you stick with it, you'll figure it out.
