I've loved the Pokemon games since I was a kid, but I never actually ended up playing them that much, I had one of the GBA games, but because of my memory I can't even remember which, I also had Black, but I never got past 6 Gym badges in any game until now so I never actually got any Legendary's until now, I have X and Alpha Sapphire, and right now I'm playing both, but I'm much farther into AS, I just captured, Kyogre, then Mesprit, then Azelf, and I have Latias of course (since he's given to you during the story) and a Shiny Rayquaza (Got as an Event Pokemon), so I didn't capture them, but I have 5 Legendary's, and I actually captured 3 out of 5 of them, I'm just curious, everywhere I looked online says that in the grind of capturing Legendary's, that you will probably use 20-40 Various Pokeballs, on each Legendary. On Kyogre I used like 20-25 Pokeballs (my guess is around 10 Ultra's, 5 Dive's, 5 Net's, 3 Luxury's, & finally got him with a Timer Ball), then Mesprit took around 20-25 again (my guess is around 10 Ultra's, 2 Luxury's, 9 Dusk's, and the 9th Dusk was the one that captured him), but then when I went to capture Azelf, I got him down to 1 HP, and I decided to start off the rain of Pokeballs with an Ultra Ball, and to my incredible surprise, the 1st Pokeball I used, the Ultra Ball, captured him, and from what I saw people saying on the 5ish sites I looked at about Legendary's, that sounds really rare and unbelievably lucky, because 1 site said you will probably use 20-40 Pokeballs, and another gave obvious advice like if it's night or in a cave to use a Dusk Ball, if it has been a lot of turns to try a Timer Ball, etc... and then after all that on various balls to use in various situations that are better then an Ultra Ball, they said to do that because if you went with just Ultra Balls that you will use possibly 40 of them, so when I caught Azelf with a single Ultra Ball, I just wanted to know if that is rare, super rare, ungodly rare, or if the websites were really over exaggerating?

Here's everything you'll need to know about Azelf

Here's how to use Azelf as a competitive battle Pokemon in the OU tier.

It is a one-off. Usually legendaries do take more Pokeballs to capture. But I have noticed that the newer games are more generous. It was much harder to catch legendaries before. Rayquaza in the original game was a pain to get to, and a pain to catch.

It's all about math really. The whole chance of catching a Pokémon is a couple of math problems factoring in various things. Here's a page detailing it, as well as giving the math problems used.

Basically, because Legendaries have higher catch rates, the catch fails more often than not, thus requiring more Pokeballs to capture. However, since it uses random numbers, there's a chance that the catch will succeed on the first try, like with what happened with your Azelf. It is quite rare, and you're lucky to have it happen to you. The other people weren't exaggerating about how difficult it is.

Story-tied legendaries have very low catch rates besides Deoxys.

Sweet, I'll take lucky!
