That's just more lies and/or magical thinking from a Trump cultist, another person who has been deceived into abandoning rational thinking and instead worshiping at the feet of their dear leader. Trump does not even have 2 million more votes than Cruz. Since when does 1.9 million translate to "millions and millions?"
More importantly, Trump only has 37% of the votes overall. Almost 2/3rds of the voters have voted for someone else. The vast majority of the voters don't want him and that silent majority will be silent no more. We will happily and proudly crush his chances to take over the party and hand the election to Hillary at the convention. That is how politics worked. If you're not comfortable playing this game, I recommend tiddly winks.
An argument could be made for "second ballot" in popular vote. He might do better.
