True to type means that if you plant a particular variety of seed potato, then you'll get a crop of potatoes that will all be that variety (clones of the original, as you mentioned)
If you grow seed gathered from a particular variety, you might get new potatoes very like the parent, but you probably won't. They might be earlier, or have a different colour skin, or not crop as well, or be ... well, different in some, or several, ways. That's how new varieties are produced. Chances are, they won't be so good as the parent as a lot of work goes into creating improved varieties, but they could be wonderful.
You could save small tubers from this year to plant next year, but by buying specially produced seed tubers, you are less likely to get diseases in your crop.
Chitting is leaving tubers in a light place until they begin to sprout.
