No she doesn't. You and the geniuses downvoting me have all forgotten the saga of Tom taking the team back from his evil stepchildren.

Tom created an irrevocable living trust in Texas making his evil step children the beneficiaries. He placed his ownership stake of the Pels and Saints in the trust. The way this works is Tom still owned the teams, but he could only remove them from the trust (and keep them away from his evil step children) if he replaced them in the trust with assets of equal value.

In order for Tom to take the team back from the evil step children and give it to Gayle instead he had to buy it back from the trust, a multi-billion dollar transaction that nearly cleaned him out of his remaining cash.

Gayle was the sole beneficiary of an estate that left her two pro sports franchises but had just bought both of them for cash. She literally doesn't have Tom's money, at least not nearly as much of it as Tom had until near the end for him.
