TC20 legendary heroes

I’m inquisitive to know how often a TC20 produces a legendary hero, is there a ratio or just luck?
Been playing for ages and only have three 5☆ heroes while people I’m aligned with and have been playing only a short time have many more!
How can I improve my odds of gaining legendary heroes?
