I already filed my taxes and said my parents could claim me, but it turns out they can't, Will that make a difference on my tax return?

Not as big a difference as it did in past years. You now get a $12,000 standard deduction, whether you are a dependent or not.

Simple rule: if you had less than $12,000 of wages or self employment (Schedule C) and no other kind of income, your tax is the same either way.
