Am I at risk by participating in this thing that looks like a scam?

Hi, something very weird happened to me today:

Someone I didn't know contacted me on Telegram, presented as working for Junto digital marketing firm. They said they're "hiring" people to like Tiktok posts and pages of their clients, paid between 100USDT and 200USDT with sometime some extra bonuses.

Obviously that looked like a scam, but I was curious about their modus operandi, so I replied as if I was interested and oblivious to their real intentions. They said we'll start with a test to show me how it's done, that I had to follow and like one video on the Tiktok account "paris.zigzag". I did it, sent a screenshot, they asked for my age which I provided (no ID sent ofc). Then replied, linking me to another telegram profile, saying "this is our receptionnist: send her this payment code (something like T-XXXX-XXXXXXTGM) and she will send you the funds".

I contacted this person with the "payment code", she asked me a few things (complete name, age and occupation, for which I all lied just to be safe). After that I sent my TRC20 USDT wallet address... And received 10USDT a few minutes later??

The "receptionnist" then said to wait for me to be assigned to a "work group". Since this, I received no other messages from those Telegram accounts and the first one seems to have been deleted.

Does anyone know what the hell that was and what might be the modus operandi of this scam? Also am I at any risk by providing my wallet address and receiving some money from people I don't know? (I live in the EU)

TL;DR I ended up receiving 10UST from something that 100% looked like a scam and I'm very confused about this
