I was trying to find 2 games MMA Team Manager gog version and Paradise Cracked old game english version on GoG.com

Maybe it's a misunderstanding but you seem to speak like GOG is not a legitimate site. You don't just add games on GOG. Developers and distributors make arrangements to sell their games on this platform. There is a wishlist section where you can vote for these two games to let GOG know that there is interest in them.
Also, why GoG, with a small caps o both times?

Is a MMA team manager like one of those yawnsome soccer management games whose longevity and existence have baffled me for nearly 30 years?

And if so, I can't say I really see there being anything resembling an audience for such a game.

As you already found out: these two games are not available on GOG.

But nobody is stopping you from putting MMA Team Manager on the community wishlist (see attachment).

For your second game, there exists already an entry on the community wishlist:
