This study shows that most subject simply pooped it out and there was no sign of it in their guts:

"After 25 healthy volunteers ate a generic probiotic with 11 strains of “good” bacteria, they all had probiotic bacteria in their stool, which the research team expected. But when doctors did the endoscopy to evaluate their intestines, they found that probiotics had only actually “stuck” and grown in a few people."
I personally take probiotics occasionally for gas control and it works. It doesn't have to stick to my gut, as long as it helps generating less gas while it is in my system, I am happy with it... Don't take my word for it, if you have beer farts, just take probiotics before drinking and report back. You and your lady friend are welcome!
Interestingly, another article about the same study mentions only 15 volunteers, so we have a problem of either small sample size or faulty reporting:

But they also came to another interesting conclusion:
"The outcome was striking. For a start, the microbes found in faeces were not representative of those that had colonised the gut. “Relying on faecal samples as an indicator of what goes on inside the gut is inaccurate and wrong” says Elinav."
In plain English, relying on shit samples is shitty at best.
"The research also showed that while probiotics colonised the gastrointestinal tract of some people, the gut microbiome of others just expelled them. There was no way of telling from their stool sample which category people fell into. “Some people accept probiotics in their gut, while others just pass them from one end to the other,” says Elinav. They found that the probiotic colonisation patterns were highly dependent on the individual. That tells us that the concept that everyone can benefit from a universal probiotic bought from the supermarket is empirically wrong, he says."
In plain English: people are different.
But what is alarming that it can be dangerous:
"Probiotic bacteria readily colonised the gut of everyone in the second group after antibiotics had cleared the way. However, the researchers were surprised to find that this prevented the return of the person’s normal microbiome for up to six months. “The probiotics very potently and persistently prevented the original microbiome returning to its original situation,” "
