I think it goes without saying that your personal connection with the recruiter encouraged him to work extra hard to get hired. Some recruiters are really good - though I haven't used them myself, I know a number of folks who used them to their advantage. Of course, it's all about how much the recruiter likes you too - if they are indifferent to you, they will not put in that extra mile.

I don't think recruiters ended up recruiters due to familial circumstances though - many of them I know worked in the same fields they help recruit to, and largely pulled out due to burnout or some other unintentional consequences.

Also it is to be noted that recruiters are usually the only way forward once you reach a level of seniority - you won't be able to cold-email after a while.

My comment was largely targeted at the above comment which said that it's only possible through being part of the privileged.
