Short answer: No.

Long Answer: I've met plenty of younger people traveling through SE Asia, though usually in groups of 2-6 it shouldn't be hard for you to meet people as a lot of people are there traveling alone and in the mood to be friendly and open - not like they are keeping their head down going from work to home like back in the 'real world'. As long as you are mature you should find people willing to have you tag along with you on some of their own adventures. A lot of Europeans on gap year after university who aren't too much older than you, but also a fair shake of people just out of highschool and hoping to have an adventure before starting university.

There may be some dry spells where you aren't meeting too many people to interact with and the usual advice would be to go to someplace like Vang Vieng or 4,000 Islands where people are partying. However, I've actually had better luck meeting people who were fun to hang out with in places like Savanakhet or Tad Lo which were smaller and you ran into the same people each day while just hanging around.

True enough, though when I've been traveling I will usually meet local people for a night of hanging out at a local bar or cafe, maybe run into them in the same restaurant for a couple of days in a row. I've found Laos was the place this happened most often, though I've also traveled alone most often in Laos.
