Driving and working time the same thing? Or not? What’s right now?

Hi, Is working time and driving time the same or not? I think that I can have 9 hours of pure driving time on the day and can carry out loading and unloading activities in between, so that I can also be able to travel 11 hours, if I have only been driving 9 hours in these 11 hours. My digital tachograph distinguishes at least finely between driving and working hours. Despite that I travel about 10 hours a day, I can’t even get close to the 9 hours driving time. When I start at 6 am I have to take a break between 12 am and 1 pm, at least according to the tachograph. Unfortunately everyone tells me something else, I have already heard the driving and working hours would be the same, so you are not allowed to travel for more than 9 hours every day (apart from the exceptions). So when I start at 6 am I have to stop at 3 pm, even if I do 5 hours of loading and unloading during this time. I didn’t even get a clear answer at the driving school, I asked three times and every time my question was apparently misunderstood!? I then gave up…
