Some CA convictions, like your DUI, can be 'expunged' from criminal records by proper application and Petition to the court, but ONLY IF all terms of sentencing and at least one year of probation are completed, and if there are no new charges pending. If successful, the conviction would be withdrawn and the charges dismissed. Expungement does NOT clear, 'remove' or erase the conviction, but does change the record to show 'conviction reversed and dismissed by expungement'. It doesn't disappear. The conviction is still a 'prior' or 'strike' for purposes of repeat offense. It still shows on your record that is accessible to government agencies, law enforcement, courts, background checks, etc. Expungement specifically does NOT restore firearms rights lost due to felony conviction. Expungement will help in obtaining and keeping employment. When applying for a job in the private sector, in response to any question concerning your prior criminal record, you may legally deny that you were arrested or convicted of the offense.
