Of course, this model isn't an example of neatness or how figurines should be made. But it clearly shows that a person doesn't need to spend dozens of hours creating a base model, especially if they have the skills.
No offense, but you spent 40 minutes sculpting a crooked mess. It will take you another 6-8 times that amount of time just to finish the sculpture. Then, Google what retopology is and how long it takes (because you obviously weren't paying attention when I explained it). Then, add roughly the same amount of time for texturing as you spent on these stages. In the end, it will take a couple of days to create a simple character model. That's normal. And I don't understand your shock. If every newbie who just discovered Blender could create a game-ready character model in 3 hours, do you think anyone would pay for this job?
Anyway, I won't argue anymore. You can believe whatever you want. You can continue to think that sculpting a nonsensical mess in Blender in 40 minutes, which still needs a lot of work, is the same as creating a decent model in 3 hours. Honestly, it's ridiculous to even talk about it. Don't you trust me? If you need proof and real numbers, consult Google or check out a graphics forum, like our render.ru.
Once again, trying to do something and learn is great. If you're trying to encourage people to learn 3D, that's great. But saying "it's a piece of cake, guys" is simply not true. Creating good models independently is quite possible and, in theory, beneficial for you. But be prepared for it to take more than 3 hours and require effort. Good luck to everyone in their endeavors.

For example, here's a model I made a while ago.
It's very bad and rough; if it doesn't seem that way to you, it just means you don't have a trained eye.

But even this model took me about 10 hours in total. Yes, it was a long time ago, and I was just getting acquainted with Blender and learning anatomy, but it still took 10 hours. Now, I could probably do it in half the time. A professional might be able to create such a model in an hour or two. But it's still a rough draft that needs a lot more work. Do you understand?
