But the growth charts answer your question definitively.

Does the chart imply that, if you are X height or weight now, then you have a real good chance to reach Y height or weight in the future?
No, it doesn't work that way. It means that for a large population currently at X height or weight, in the future the population on average will reach Y height or weight. For any individual, who knows?
