The 41-year-old coach is refusing to get carried away by Los Blancos' two consecutive draws and insisted that he did not watch the controversial affair at El Madrigal
The Santiago Bernabeu outfit dropped points in the league for the second match in a row to allow Barca to get within six points.
"We are behind them, but it is clear that it is better for us that they draw than win," Guardiola added.
"Six points are fewer than 10, but the difference is still a lot. Madrid have two draws in a row, but it does not mean they will draw the rest of their games.
"What usually happens is that Madrid win almost all of their matches. That is why the distance is so significant.
"That is why I said the Liga title was lost. It was a comment purely based on sporting matters."
Guardiola conceded that the stalemate at El Madrigal was favourable for his own side, but refused to comment on Madrid's criticism of the refereeing decisions.
"I did not watch Madrid's game against Villarreal, so I have no opinion about it," Guardiola told reporters at a news conference.
"When I learned about the draw, I was happier than I would be if they had won, but I slept at night the exact same way.
"Some of us have families, wives and children. I have watched many of Madrid's matches, but not this one."
The 41-year-old coach then rejected the notion that Madrid are in crisis and insisted that the distance between the two clubs is still considerable.
Looking ahead to Saturday's match against Mallorca, Guardiola had words of praise for Joaquin Caparros' side, who lie in 12th position in the Liga standings.
"They are going through their best moment in the season," he noted. "They have a very intense and dynamic team and put a lot of pressure up on the field."
