Definitely not. The way how they work is different from one another. If you'll understand the principle of gambling, it's pure luck based. Thus, there is really no professional here. You can't help yourself from losing in gambling if your luck isn't favorable of you but to stop. Meanwhile in day trading, you might lose continuously but you can be professional there with decent experiences and knowledges of course.
This is the right definition of day trading in its sense. When you are a gambler for 40 years all of your winnings are coming from your own luck, not your skills. Whenever you put your money on the table, you only waiting for the unknown results. Whether you win or lose, it's all about luck. On the other hand, Day trading will give you tremendous experiences in the long run which will become a skill after so many day trading you had through the years.
Gambling games will certainly use luck because they only want to see how the results that come out of the casino can be changed by the dealer so this will be a game with high challenges, high risk gambling, relying solely on luck, different from daily trading. concentration to read market movements or can also be called its analysis must be precise.
For me, daily trading will be far better than gambling, relying only on luck because the reality is so.
