Not exactly. Teenagers raised by single parents are more likely to participate in illegal activities, but not categorically "likely". Some single parents manage quite well, particularly if they have adequate and reliable income that allows them to spend time with their child(ren).

Parental negligence is really more to blame, though again it is not always the direct fault of parents who may be operating under very difficult socioeconomic or other circumstances which make their involvement more difficult. Some parents can also be over involved, which can contribute to behavioral issues. If by exposure to violence you mean real violence in the household then I agree, but if you mean violent media the evidence simply does not support that conclusion. By family disintegration I assume you mean separation or divorce, which is disruptive but does not necessarily lead to overall negative effects on children.

Poor education also does not inherently lead to delinquency, unless there is a resultant lack of opportunity which is usually but not always the case.

Peer group influence is another important variable you left out, and parents may have somewhat limited control over that. Genetics plays an important roll too. There are other less significant but still relevant variables as well, which suggest that parents are not usually entirely to blame (and sometimes may even be largely without fault).
