Sports gambling has been legal in the UK since 1960. Gambling wasn't seriously problematic in this country until 2005, when regulations were substantially liberalised. Pre-2005, sports betting was something that old men did in dingy backstreet shops; post-2005, it became a widespread social phenomenon, turbocharged by advertising and the growing influence and accessibility of the internet.
There's a false dichotomy between prohibition and laissez-faire, which the US seems particularly prone to. You've seen similar issues with the decriminalisation of cannabis, where many states seem to have switched abruptly from criminalisation to a fully-fledged commercial market. There is a broad spectrum of other options in between those points that tend to be under-discussed.
You can ban gambling advertising, as Italy did in 2019. You can set limits on maximum stakes or impose regulations to make gambling products less attractive to new customers and less risky for problem gamblers. You can have a single state-controlled parimutuel operator. Gambling does cause harm - whether it's legal or not - but it is within the purview of legislators to create a gambling market in which harm reduction is the main priority.
