I just did a solo raid against a 5-star Morpeko (red beam). I thought it was always a 100% catch rate but I didn't catch it. I used an ultra ball and this is in Isle of Armor DLC.
Each Pokémon has got a specific Catch Rate. If you play Solo without going online, for any standard Max Raid Battle or Gigantamax Raid Battle away from the Special Events will have guaranteed capture. However, if you go online or play with other players locally this changes. When you join other people's raid battles, you will have the standard rate of capture for the Pokémon based on its species, but Gigantamax changes this. If you're hosting the raid, you have a higher chance of catching the Gigantamax but if you're joining in, the rates are on par with Legendary Pokémon. All the Balls will have the usual effect.

Hope I helped!
Nope. Not 100%. If you want a better chance at catching them, use Dusk Balls and Repeat Balls

No, they do not. I've failed to catch multiple Raid Pokemon because I'm cocky.
