Then it means its just way to introduce them to the term bitcoin.
Those advertisements have their own commercial purpose, they will not invite you towards change and freedom by introducing certain cryptocurrencies (say bitcoin) voluntarily, they just focus on their services/platforms such as casinos, games, exchanges. So, it will come back to the viewer's interest in those services.
They may or may not even get involved with the crypto directly. I am not sure how they take the statistics from the TV industry on how many users viewed but soon will be looking into how much growth that particular ad gave to coin switch. If they somehow publish this data then we can know for sure how much impact TV commercials has on the bitcoin or crypto as whole.
But I think there is no solid study on the math that you did right? Like its too less ratio of 0.1% getting turned into crypto users from that ad views. Hell low!

Don't know how it is in your country, but you won't find crypto based ads in my country showing on TV. And I can say that nowadays advertisers prefer internet platforms (like blogs, youtube, even in apps) over TV shows because they have a wider, unlimited audience reach, and can customize targeted impressions based on audience interests (cookies).
