It is true that some people are sometimes just curious and want to experience playing on different sites, so we should not immediately assume that they are addicted. Sometimes, a single site can be enough to cause a gambler to develop an addiction, it all depends on how well the gambler controls themselves and sets their limits.

I think that if they act responsibly, there will be no problems when they try to register on multiple sites. In my opinion, many gamblers have registered on more than one site, and of course each of them has their own favorite site. It could also be that those who register on many sites are trying to seek luck and win a jackpot because they are considered beginner gamblers.
