Champion jockey Kieren Fallon often gave his opinion on horses to England footballer and horse owner Michael Owen, Fallon's trial has heard.
Kieren Fallon often gave race tips to people, the court heard
He also gave tips to Philip Sherkle but denies any role in an alleged £2m conspiracy to lose races so that a syndicate could win bets.
Mr Fallon said he thought his tips were only for Mr Sherkle to bet and did not know if they might be passed on.
Mr Fallon, Mr Sherkle and four others deny taking part in an alleged plot.
It is alleged that the syndicate was run by professional gambler Miles Rodgers, who has also pleaded not guilty.
At the trial on Wednesday, the court heard that Mr Fallon had told detectives in an interview: "I thought that by texting Phil he was having his own couple of quid on it.
"I do that with a lot of people. Michael Owen, every day texts me."
And he later said: "Most guys, like I say Michael Owen, would only ring to talk about races."
Mr Fallon said he did not know what Mr Sherkle did with the tips: "What Phil does with the information is out of my control."
Asked if he was part of a conspiracy, Mr Fallon replied: "I never stopped horses, never did and never will."
Police asked Mr Fallon about texts between him and Mr Sherkle after he won on the Queen's horse Daring Aim in July 2004.
He denied a suggestion that he had indicated he would lose by texting "n" to Mr Sherkle.
The next day Mr Sherkle texted: "If u don't speak to me now I won't be able to help you."
Mr Fallon replied: "They will take my licences off me if they drift like that last night. They are watching me."
Asked about the messages, Mr Fallon told police: "It's a worry about horses drifting."
Mr Fallon, 42, of Tipperary, Republic of Ireland, Mr Rodgers, 38, from Silkstone, South Yorkshire, Shaun Lynch, 37, of Londonderry, Northern Ireland, Mr Lynch's brother Fergal, 29, from Boroughbridge, North Yorkshire, Mr Sherkle, 42, of Tamworth, Staffordshire, and Darren Williams, 29, of Leyburn, North Yorkshire, have all pleaded not guilty to being involved in the alleged race-fixing scam.
The trial continues.
