There’s the unified rules of mixed martial arts, which generally sees one fighter against another, and the fighters of today usually can strike, clinch, throw/takedown, and fight on the ground, and fight their way back to their feet, too. This is sport and the athletes deserve a lot of respect. Classical martial arts can include sportive elements, can be geared more toward self defence / self protection, can be about preserving the art, and it’s not always about winning sports matches or beating people up.
