I haven't been able to find death rate statistics for people aged 18-30, so I can't really compare the numbers with strictly facts. There is an article from the BBC from 2015 that claims that the number is in line with what would be expected from that age group:
> The point officials are making is that there are about half a million Indian workers in Qatar, and about 250 deaths per year - and this, in their view, is not a cause for concern. In fact, Indian government data suggests that back home in India you would expect a far higher proportion to die each year - not 250, but 1,000 in any group of 500,000 25-30-year-old men.
