    If we change above sentence as below - adding by before the time phrase, please advise whether it makes any difference.

    Next year - vague/at some point next year
    By next year - when the next year starts, 10 years will have been achieved. Presumably, the anniversary is close to lớn the kết thúc of the current year or at the very start of the next year. However, I personally would more likely assume kết thúc of current year.
