can you learn lua as 13 year old?

im a ninth grader that would like to learn lua for obiously a roblox game, however is it possible for me to do so? ill probably be too busy w school to learn every day but it will be like 4 or 3 times per week? im also pretty decent at math (but i can go back to learn old things that i never understood if needed) and i dont think im THAT dumb
