No, lets be real for a moment
Everyone who says Kaiji part 3 is simpler than Akagi because it's "simplified" mahjong is wrong in the sense that P3 goes quite indepth into the meta and possibilities given by this "simpler" ruleset. There's a lot of variables at play and reading that part with mahjong knowledge will let you appreciate stuff like Kaiji balancing offense and defense.
HOWEVER it's true that this game is a game where two sides just take turns discarding tiles and hoping to not discard the one their opponent is waiting on. No calls, no tiles stealing, and the hand building happens prior to this. In that sense it's easy to follow.
My suggestion: get a list of yaku (pic related) alongside you as you read this part. The restrictions are simple: you need 4 points (han) or more in your hand. 1 han is provided implicitly (riichi) to both players, so Kaiji and his opponent can do multiple tactics to get the 3 remaining hans: honitsu, combination of pinfu/tanyao/sanshoku, bonus tile (called "dora") which grants 1 han for each one you have...
It's not really complicated as long as you check the sheet to see what Kaiji is building. It's very straightforward, actually!
All you need is to make sure you understand a winning hand in mahjong is 4 sets (sequences of three tiles, eg 345, or same like 444) and 1 pair. You'll be waiting for the last tile to be discarded by your opponent, so there are multiple patterns of tiles you can wait on! The more, the better. For instance, if you have three sets, one pair, and the last set to be completed is currently 23, that means you can win on 1 (123) or 4 (234), which is a good situation! On the other hand, if your last set is currently 13, you can only win on 2, which is a tough situation...
