No, they are different.
^.{2,}?$matches strings whose length is at least 2 (as seen on rubular.com):By contrast,
^.{2}$only matches strings whose length is exactly 2 (as seen on rubular.com).It’s correct that being reluctant,
.{2,}?will first attempt to match only two characters. But for the overall pattern to match, it can take more. This is not the case with.{2}, which can only match exactly 2 characters.References
