Friendly reminder that although you can homebrew it to be like this if you want, in the official D&D 5e lore, Elves and Dwarves mature at the same rate as humans, so they’re all adults at 21.
Culturally is a little different, much like some older humans still view people in their 20s as “kids”, elves and dwarves will only consider themselves to be truly adults after at least 100 years or so, but that’s just a social stigma, not how they are biologically.

And if you want to play by RAW, they’re born with all their stats, knowing whatever language they know, and and the same size class as adults.
