The rumored "degeneracy" of some (famous) poker players cannot be addressed without first defining our terms.
A degenerate gambler is what used to be called a "Compulsive Gambler"
By late 20th century that term had evolved into "Pathological Gambling."
The stakes at which gambling devolves into "degeneracy" is entirely relative to the gambler's financial status. Some gamblers cannot (rationally) afford to gamble at all. They may have no discretionary funds. they may be heavily in debt or even commit crimes to obtain cash for gambling. Clearly there are persons who are wealthy enough to lose 6 and 7 figure sums without "feeling" it.
Similarly, excess time spent gambling can suggest degeneracy.
Unless one "has the best of it" then to forego food and sleep to gamble smacks of degeneracy as swell. Ignoring one's spouse, family, employment, etc. etc. reeks of degeneracy.
Need I go on?
The "whale" stakes (that someone like Phil Ivey shoots craps for), is not, in and of itself, an indication of "degeneracy."
Anecdotally speaking, the legendary, near mythic poker immortal, Stu Ungar, would think nothing of winning hundreds of thousands of dollars at the poker table only to be broke by the following day after betting everything on sporting events about which he knew nothing.
Stuey, "The Kid" Ungar was a (definitively) degenerate gambler.
It is a fact that a handful of the biggest names in poker will shoot craps, play BJ, or play golf, etc. for extremely high stakes. They are often people whose lives, (financially speaking), are quite unlike those of most civilians.
After all, if you are used to winning and losing 5 and 6 figure sums at poker, then the (essentially) mindless games of craps is a seductively stress-free form of relaxation - compared to high-stakes poker.
