Assuming that Electrek's quotes were accurate, this was misreported by Reuters, then copied by CNBC and perhaps others. According to the quote on Electrek, Musk actually said that Tesla would run out of the $2.2 billion they had in cash at the end of Q1 within 10 months at the Q1 burn rate. In other words, he totally ignores the raise of an extra $2.7billion since then and doesn't mention it in the Electrek quote - but Reuters reported it differently, saying that Musk was commenting that the $2.7billion raised recently would run out within 10 months at the Q1 burn rate.
