I would call that excellent value for money if you can buy that first camera & lens for 50 pounds or 75 bucks or whatever and learn and keep with it. That said, I did a lot of my learning on a K-5 II that I still own, so I sort of lived out exactly what you're describing. I think either path works and the important thing is getting a camera, getting comfortable using it, and use it a lot and often.
There are so many 6 MP images I own, that I wish were higher resolution, it's the pain of that scenario that keeps me advocating 12 MP. I still have the 11 8 x10s I took to get into Ryerson Photo Arts all those years ago. In a sense a film image is future proof. And since they were all taken on 120 film they can be reproduced at any size I'd be interested in up to 16x20. On digital, you should be a little more thoughtful.
At 200 DPI, 3000x2000 gets you 15 x 10, not even an 11x14. At 150 DPI, my current minimum for printing, you could get up to 20 inches. You need to think ahead. How you will display should be part of the decision, not just now but in the future. After all, the main purpose of most photography is to display an image on something other than your camera.
If you are the kind of person who never printed film larger than a 4x6, a 6MP camera will be adequate.
My favourite 35mm film print size was 11x14.
I've grown to appreciate much larger prints and displays these days. My average print being 16x20 and my average canvas being 20x30. I understand not being able to afford better, but it's also good to decide whether you want to go cheap now to upgrade later, or wait a bit and start with better.
Of course if you don't even know if you like photography, intentionally temporary gear might be an option.
