From what I have seen, my sons friends who are OTD, were not achieving success in learning, in any way. So they would not be insprired at all in learning Limudei Kodesh, so this influenced their next steps, in my experience, knowing these boys since they were babies. Whether they are physically abused or mentally, iow, the Yeshiva where he went, does not hit, but treated the non achiever like garbage in many ways. If this could be fixed relatively easy, it would help alot.
Probably you may find a strong learner who is OTD, but I would say the majority not.
