Seized cartel assets aren't his to allocate. That money is already earmarked to the local law enforcement agencies that seize it, and only after it is released by the court which can often take years. IE, it isn't the executive branch's money to take and allocate. It first has to go through the court system (4th and 5th Amendments) then current law allocates it to the local law enforcement agency who seized it (18 U.S.C. § 982). It would have to go to congress to change the law to allocate that differently.
Translated, like usual, he is promising things he can't promise and spending money he can't spend.
