In the news they say that
Israel hoped to become the fourth country to land a spacecraft on the Moon. Only government space agencies from the former Soviet Union, the US and China have made successful Moon landings.
E.g. haaretz, BBC
Why they don't mention the Indian Chandrayaan-1?
The BBC article that I quote here even provides a picture from NASA with the list of successful moon landings that includes a station from India.
Another question: why they call it low cost? According to the same BBC article,
The project has cost about $100m (£76m) and has paved the way for
future low-cost lunar exploration.
Wikipedia says that the cost of the Chandrayaan-1 project was US$54 million.

It's a good point you make. Presumably they are talking about soft landers, not impactors, though.

Chandrayaan-1 hit the Moon at high speed and did not survive its "landing", which would have been much more difficult to engineer. (Its successor, Chandrayaan-2, which will actually land, is expected to cost $125 million and has taken more than ten years so far, as opposed to the three years for Chandrayaan-1.)
As far as cost goes, besides India's own (still unlaunched) soft lander that costs $25 million more than Israel's attempt, compare the costs of the US Surveyor program. NASA spent $469 million in the mid 1960s to launch seven probes, five of which successfully landed. Most of that money went to developing the technology needed for all the probes to work, and each probe cost a small fraction of that to actually build. Adjusting that amount for inflation, you get almost $3.8 billion in 2019 dollars. So if we had to start from 1960s technology and launch a new probe to land on the Moon, the cost would probably be somewhere around there. That's nearly forty times the pricetag on Israel's project.
