Umamusume is carried in global by:
>le funny hors girls are based on real hors and reference a bunch of heckin real hors facts and epic history
>streamer attention from Northernlion which in turn spread attention to bigger faggots like Asmongold and Ludwig which gave the game a lot of exposure (free marketing even if it was short-lived)
>anime series is unironically very good compared to 98% of modern anime slop
>roguelite gameplay is actually endearing while requiring minimal execution or thinking, makes it very easy to stream the game while talking about literally anything else which makes it a good choice for western streamers
>feeds into both raising sim autists and casual players who would have never known the game existed if not for free marketing from points above

Now let's see what idolm@ster has:
>anime idols without any quirky backgrounds that would capture the west's attention
>anime idols in an era where vtubers are more popular
>good music videos (gakumas) when the west skips the winning lives for the most part anyways
>songs made by famous composers like giga and Minami that the west gives no fucks about
>gameplay is more of a deckbuilder and the trainings/lives require far more effort to high score, making runs last longer on average while you can still be easily screwed over by RNG in gakumas version of inheritance; audience more prone to dropping the game enmasse
>never even hit the highs Umamusume did during its peak months, less popularity in its own country let alone global
>Mao's story line would unironically cause mass westoid seething due to the Producer telling her to stop acting boyish and she listens instead of finding a different answer (the scenario writers include the fucking Oreimo author)

Gakumas would be COOKED if it ever came to the West.
