This is not true. For all appeals, the grounds for winning are:
a) the admissions arrangements did not apply with the admissions code (and if they did the child would have been awarded a place)
Or
b) the admissions arrangements were not correctly and impartially applied (and if they were the child would have been awarded a place)
Additionally, for appeals that are not infant class size appeals, an appeal can be won on the grounds of prejudice. Prejudice is precisely about personal circumstances.
To win an appeal on prejudice grounds, the panel must be satisfied that the school is not so full that it can't take another pupil, and that to take another pupil will cause less prejudice to the school than denying the place will cause to the appellant.
Generally, parents are expected to get their children to school unless they qualify for transport, so logistics is a bad grounds for appeal. In KS2, if the school's case was very weak and you had very strong reasons why it impacted the child, it might fly but it would be unusual.
