This is actually untrue...
One of my friends on facebook made this post after the vote:
"1,545,382 16 to 17-year-olds living in the UK as according to mid-2013 data: our population is only getting older, so presumably there are fewer 16 to 17-year-olds now, but we'll still use this figure.
100% of this number can be part of the electorate.
we assume the number of 16 to 17 non-citizens studying inside the UK is roughly the same as the number of 16 to 17 citizens studying outside the UK. turnout might be 36%, so 556,337 people would vote.
turnout for 18-24-year-olds was 36% as according to Sky Data: this would potentially be even lower for 16-17-year-olds due to the trend of turnout increasing by age (and starkly vice versa).
72% of these votes might be to remain, meaning 400,563 more remain votes.
conclusion: remain might have lost with a little bit less of a gap (precisely 3.2% of a gap)"
It doesn't matter. Realistically, Brexit would have won either way.
Although I'm not happy about it either, you have to deal with it.
