Yes but according to some of the people there Elon didn't communicate through any of the proper channels to try and help. He only did it through social media or more publicly, and according to one of the diving experts there his submarine idea was never ever going to work. Just seems like a publicity stunt to me.
SpaceX team met w/ Admiral Apakorn Youkongpaew and members of Thai Navy yesterday in CEI to train them on the mini-submarine. Navy believes it could be helpful and practical in future rescue efforts and will conduct further testing in Bangkok in the near future. pic.twitter.com/oJuVAAO7js

The former Thai provincial governor (described inaccurately as “rescue chief”) is not the subject matter expert. That would be Dick Stanton, who co-led the dive rescue team. This is our direct correspondence: pic.twitter.com/dmC9l3jiZR

I didn't like how "PRy" it seemed at first but actually making it proves otherwise imo. Building the sub would have cost a lot of money and would just not be worth the low amount of publicity. It's not like this is a company that needs all the attention it can get. It's really only useful from a PR point if the sub is used and included in every single broadcast about the event.
Also in unrelated news!!!!!!
In a month or so
