While you can increase sensitivity of the camera (higher ISO), this tends to me less colour depth and more sensor noise. As a general rule, lower MP for a given sensor size (in the same generation of cameras) will give you better low light performance. Mirrorless cameras tend to be a lot quieter than DSLRs (no mirror slap), but light performance tends to be not as good as with DSLRs. Sports and action photographers tend to have the most expensive camera bodies and fastest lenses available to do this kind of shooting at costs that are well above your budget.
