The Villa boss has been linked with Tottenham striker Defoe and Stoke counterpart Jones in recent days, with Darren Bent currently his only available proven goalscorer.
"They are two top, top players, those lads. But that's not going to happen here," he said.
"I have seen the rumours linking us with some players but a lot of them aren't going to happen."
He added: "I have never stopped looking. Someone might come in.
"We'll have to wait and see. You can never be quite sure until someone walks through the door and they are actually here.
"It's difficult because of the prices and that's a hard thing. I think it's well documented the type of players I'm looking for.
"They have to want to succeed and be hungry to do it. That's another issue you have to deal with. If they tick those boxes than we will have a look at them."
Looking ahead to the anxious hours leading up to the window closing, Lambert said: "I don't like deadline day. Especially the January one because sometimes you end buying for the sake of buying.
"You can panic. I'm not a big advocate of it."
Ahead of their home clash with Everton tomorrow, the Scot said: "I can understand the frustration because I was frustrated myself.
"From back to middle we did fine. You can't have that much of the ball and not create a chance and that is something I have to rectify."
It emerged this week that Lambert has banned his players from using their phones and laptops around the Bodymoor Heath training complex.
However, the former Norwich chief has sought to play down his reputation as a strict disciplinarian.
"My own phone doesn't work so if mine doesn't, no-one else's does," he said.
"It's a place of work and a profession. They are professional footballers.
"I don't need people Googling things and all that. We're here to play football and you respect the player and have discipline like anywhere else.
"I don't apply a steel rod or anything, just certain things we will try to implement."
He added: "They are here to work. Football is a different game. It's an environment in which you want them to train and work hard.
"They need to focus on it and do everything you can to win. I have no problems with the players."
Striker Nathan Delfouneso will be available to provide back-up to Bent tomorrow after a thigh injury while defender Chris Herd is fit following a similar problem.
Striker Gabriel Agbonlahor (knee), defender Richard Dunne (groin) and winger Marc Albrighton (foot) are still sidelined while youngster Samir Carruthers has an ankle problem.
