Not what has happened in the UK, where sugar tax has been a thing since 2018. It's now actually quite hard to find a sweetened drink - almost all soda-style beverages now are "zero sugar", sweetened with artificial sweeteners. Nobody is buying sugar and pouring it in. Nobody.
It's a little too early to determine if this has slowed the prevalence of diabetes in the population. One problem is that other studies have shown that drinking artificially sweetened beverages with foods means many people end up eating more calories of food - the brain is looking for calories indicated by the sweet taste its not getting from the beverage, so compensates.
It's a complex picture, but sugar taxes seem to be a reasonable way to get sugary drinks off the shelves.
