No, they aren't the same. Unfortunately, googling decriminalization vs legalization gets me articles that state the exact opposite of my understanding. As I understand it, decriminalization means making no law against it. Legalization means making laws about it that boil down to regulation. Thus, decriminalization is more free.
This article seems to be generally in line with my understanding:
Example of making it worse: From what I gather, prostitution in Las Vegas is mostly run by the mafia and legalization has not led to women being free to be their own boss, set their own hours, etc. Legalization of prostitution often means sex workers are subjected to a lot of rules and regulations such that it becomes akin to wage slavery rather than freedom to pursue work independently like a small business owner.
I will suggest Obamacare as another example of regulation making things worse. I'm quite poor and being hit with harsh financial penalties on my taxes this year for failing to have full coverage for all of last year. Prior to Obamacare, I could just forego having healthcare and the government did not get all up in my business about why I did that and whether or not I was allowed to do that, etc.
My support of decriminalization of prostitution comes from having read Working: My Life as a Prostitute
by Dolores French. Prior to becoming a prostitute, she was a political activist.
The reason you get those google results is because your understanding is not consistent with how other people use the words. Your suggested usage is reasonable, but it's not the usage that is common, and I suggest that you change your understanding.
Legalization has always meant "making it legal", which in most societies means "removing laws that make it illegal" (though it might mean something different in North Korea, if you see what I mean).
Decriminalization is a wishy-washier idea, that includes lightening or removing criminal penalties, while potentially keeping other penalities. For example, changing indictable offenses to non-indictable offenses (in the U.S. that'd be roughly equivalent to changing felonies to misdemeanours).
Prostitution should be legalized, not merely have the penalties lightened. And that alone is not sufficient; legal regimes that legalize the actual act of sex-for-money, but still force most prostitutes to hide from the cops (I'm looking at Canadian law, here) are still inadequate, because such regimes still victimize sex workers (consensual or otherwise). It's simply a human rights issue.
I also think it's clear that some degree of regulation is desirable, but I think that reasonable people can disagree on this.
My understanding of the difference is rooted in the opinions of Dolores French who was a sex worker and political activist. She advocated for decriminalization, not legalization, because it was more beneficial to sex workers. I find some articles that fit with that framework and some that don't.
I don't think it's just me. It's a little more complicated than that.
I do try to be mindful that the words get used inconsistently and I do try to make a point of clarifying my intended meaning. I'm human and I don't always remember that this is an ongoing issue.
I have provided both a link to an article that communicates my understanding of the topic as well as cited the original source where I got the info, plus stated as clearly as I can that googling it may lead to additional confusion because articles on the topic are contradictory. Some agree with my understanding. Some say the opposite.
I have no idea whatsoever why that would be reason for you to turn this into a personal attack and justification for apparently your personal frustration with me. My understanding is you are British. You could more charitably chalk up any communication difficulties between us to cultural differences and to being "separated by the same language."
