My initial thought was “huh? Of course they wouldn’t want to go to school in Gaza…”
The most generous interpretation of her remark that I can come up with is that she’s saying all these kids want a free Palestine but wouldn’t be brave enough to do the freeing themselves.
Or she’s implying these kids wouldn’t want to go to school there even if it were free because, let’s face it, <something racist/classist/both>
But there are much clearer ways of expressing either thought, so it’s anyone’s guess.
