You're right. Loto does mean "lotto" in a few different languages. I like that name, although with the "time" it make take something away from the "loto" language.
Lototime.com - To me it just seems like a typo of LottoTime.com (parked domain)
SportBettingWorld.com - This is another typo as well. There's already a established website on SportsBettingWorld.com
Both are -reg fee. If you're just starting out in the industry then I would just focus on dropped domains with backlinks and traffic. Invest your money into monthly membership sites like dropday.com and find good names. Or use Expiring.org to find dropped domains that are available for reg. fee.
