USS Nevada -a newer ship- was in a sinking condition after one hit by a 45cm tropedo at PH. Unless the older Texas had gotten a refit Nevada didn´t just one 53cm torpedo might have sunk her.
USS Texas was underway, and presumably somewhat alert since she was on patrol. USS Nevada was in port with all watertight doors open and a large part of her crew ashore. I wouldn't describe her as 'in a sinking condition' either; she took on a slight list which the crew was able to correct and was underway half an hour later. She grounded later after taking several bomb hits.
Although I'll grant the possibility of one torpedo hit sinking USS Texas, I don't think it is likely.
Two? Mabye.
Three? Good chance.
