That quote is from the 5.5e PHB. The distinction is there. Page 247 in the Bigby's Hand spell. And in Chill Touch. And in Chromatic Orb. And...Notably, this version of True Strike is in the 2024 rules, which don’t use the “weapon attack” vs “spell attack” distinction that the 2014 rules had - probably due to the consternation those categories caused in cases like unarmed strikes where an attack that was not made with a weapon would still be considered a “weapon attack” because the only alternative was for it to be a spell attack. The terms “weapon attack” and “spell attack” don’t, to my knowledge, appear in the 2024 rules. There are only attack rolls of spells and attack rolls made with weapons. Even in monster stat blocks, attacks are listed as melee/ranged attack roll +X: instead of melee/ranged weapon/spell attack +X:
5.5e does in fact have melee and ranged spell attacks, which is not the case with True Strike.
