So why can’t they use this knowledge for rain on places like Texas now...and wherever drought cripples the land?

It takes a lot of energy to create gamma rays and they are dangerous. Concerning the creation of rain - There are two primary factors. First you have to get water into the atmosphere in the form of water vapor (gas). That primarily occurs over the worlds oceans via evaporation. The rate of evaporation is determined by temperature, wind speed and the density of water vapor in the atmosphere (how much water vapor the atmosphere is already holding).

The second primary factor involves converting that water gas (water vapor) into liquid water (cloud moisture). Now gamma rays help with the conversion of vapor to water. The more water vapor in the atmosphere, the more liquid water can be converted. Basically in a high gamma ray environment the atmosphere will have less water vapor and more water moisture.

In a nutshell - Your normal Texas rain was actually deposited in the Western Mountain ranges this year.
