I think it also helps that many of the talents include an element of choice (like the ability increase ones, or a bonus to attack rolls which lets you pick melee or ranged), and that they're pretty much all fundamentally "you get better at your job". 31/36 possible results on the Wizard table, for example, make you better at casting spells if that's what you want (either +1 to all or advantage on one). The other two possible results give you an additional spell known (more spells and more versatility) or a free magic item.
The only ones which I can sort of read as pushing you in a direction which might not have been your first choice are something like 3-6 vs 7-9 on the Cleric chart, where the former gives you an attack bonus and the latter a casting bonus, where maybe you rolled one and would have preferred to specialize more in the other, but fundamentally you probably wouldn't have picked the class if you didn't want to do both, right?
