I don’t know how many people use Ruby, its certainly not as popular as it was during the Rails hype, so its hard to day, and I don’t have numbers for the visual languages either, but Unreal Engine’s Blueprints has a lot of users. Max/MSP does too, and apparently a lot of artists use tools like Substance Designer to create visual materials and those tools have visual programming too.

EDIT: Media Molecules’ Dreams has a lot of users using its visual language to implement game logic! It sold about 8.5 million copies. Obviously not all people who bought it are using its visual language, but I imagine a very large percentage have at least tinkered a bit. I doubt Dreams would be as popular if it required textual programming.
