well, that what is worrying if there might be criticism or bullying after he uploads the video, maybe he can receive all the criticism or bullying but maybe his family members will also receive the bullying and it would be very sad if that happens because family members dont know what the problem is suddenly getting bullied like that and unconsciously uploading the video has made things difficult for himself and his family.
and I am pretty sure that he only bet a few times in gambling because looking at the story written by the OP he like a beginner gambler who does not know any limits and can not accept all the risks that will occur in gambling. so maybe he really felt sorry when he lost the bet and after that ignored the limit.
Her family members, who didn't know anything about her gambling, would even feel embarrassed if they saw the video of her crying. They might also feel angry and ask the woman why she did it and upload it to the internet because it just shows her stupidity to the public, which is inappropriate. She can tell her family or friends about her gambling losses but not upload them to the internet.
Even if he has only gambled a few times and looks like a novice gambler, he should not bet an amount he cannot afford. She should have realized this before she gambled, but it was too late because she had already lost her money and could not recover it. Hopefully, she is truly sorry for what she has done and will not do it again.
