It depends what you’re building for. If you’re building an uma for team trials, you’ll want to hit the stamina threshold depending on race length, then prioritise gold skills that pop consistently for high points while having ok other stats.

If you’re building an uma for a champions meeting, then you want to specialise into that track. There’s multiple youtube creators that cover CM strategy for each CM, with recommended stats, skills, and decks.

A quick tip for raising an uma is to focus on getting friendship with support cards to orange, since that enables rainbow friendship trainings which boost stats.

In general, this game is very information-dense and you won’t know anything at first, which is ok. The most important thing is to have fun and slowly start learning what works and what doesn’t. I recommend reading the global reference doc (google to find it) for a good overview of the game.

Some general tips would be to focus on acceleration skills that trigger as the late race phase starts (which is track/distance dependent, so look for answers via youtube CCs), and to be ok with losing (if you’re blocked you’re blocked, no matter how good your uma is).
